Ainsley Pierce - Consignment Specialist Message Ainsley

“ Frontline Engineering Masterpiece! Restoration and bespoke engineering at its finest. ”

This particular example is about as good as they get and has the added advantage of a unique Speedster-style hood and accompanying silhouette.

Background

Introduced in 1962 and still in production almost twenty years later, the MGB remains most people’s default idea of the classic British sports car.

The MGB is also the definitive front-engined, rear-wheel-drive roadster, offering everyday practicality alongside a genuinely sporting drive.

Simple, proven and plentiful, MGBs have lent themselves to every conceivable sort of modification, conversion and upgrade.

Needless to say, some of these fettled, tweaked and pimped iterations are better than others.

Without out any shadow of a doubt, Frontline Developments make the absolute best of them. 

But don’t just take our word for that.

Famously, Top Gear’s then host Chris Evans declared the Frontline to be “…the best car we drove through the whole of the series.” 

Frontline are to the MGB what Singer are to the Porsche 911 and Eagle are to the Jaguar E Type.

We think Frontline’s ‘Abingdon Edition’ cars are every bit as good as Chris Evans claims.

We’ve driven a few and know just how exceptionally well-engineered and dynamically breathtaking these machines are.

All Frontline creations are built around an original donor MG with heritage certification. 

Over the course of many weeks and months the firm fully restores the body using all new panels that are hand-built in Oxfordshire by British Motor Heritage to the identical specifications of the original. 

Frontline then apply their own exacting build standards to achieve levels of blemish-free symmetry, precision and perfect alignment that would have been unimaginable to workers on the original MG production line.

Under the bonnet is a 2.5-litre 4-cylinder aluminium Mazda engine with a billet crank, billet rods, forged pistons, solid lifters, variable cam timing, 50mm direct-to-head throttle bodies, Omex engine management, Mazda 6 speed aluminium manual transmission, and a 3.7:1 ratio, gear-driven limited slip differential – unless the purchaser has asked for something very different on his or her bespoke build. 

The engine generates 289bhp at 6,800 rpm – enough power to reach 60mph in 3.8 seconds (yes, you read that right) on the way to a top speed of 160mph.

Keeping that power on the road and serving the handling and grip requirements of even the most talented driver is a suspension set-up consisting of LM25 aluminium front suspension uprights with tubular wishbones and adjustable dampers, model-specific 6-link rear suspension system, and fully adjustable coil-over telescopic dampers and springs.

Bringing all of it to a smoothly controlled stop as quickly as possible are billet alloy 4-piston front brake callipers with ventilated discs, and cast alloy 2-piston rear brake callipers with solid discs. 

Frontline’s cars may be aligned to, and respectful of, the spirit of the MGs that left the Abingdon factory back in the day, but in terms of performance, capability, quality and finish, they’re simply light-years ahead.

Overview

This car was commissioned from Frontline in 2017 and registered for UK road use in 2019.

Like all Frontline cars, it has been built to the hilt and is a masterclass in engineering, building, tuning and finishing. 

We’ve taken this particular example for a spin and can attest to its blistering performance and jaw-dropping capabilities. 

With the merest twitch of your right ankle you can instantaneously awaken its animal instincts and make it set off like a nervous cheetah at a fireworks display. 

It feels incredibly well screwed together and the only extraneous rattles, clunks, moans, groans, whistles, sighs, creaks and grunts we heard were coming from the driver and passenger.

The gearbox is satisfyingly precise and notchy. The throttle responsive is very sharp, as is the quick, accurate, communicative steering, and the handling and ride are never less than grin-inducing.

The quality of the components is evident almost wherever you look, and it’s obvious that an eye-watering amount of money has been spent.

On the instructions of the vendor this car was built with a Speedster-style fabric roof configuration because he didn’t want the beautiful bodywork to be showing rows of studs and clips for tonneau covers.

Consequently, the Frontline fabricators and metal whisperers extended the length of the section between the boot lid and the edge of the cabin to ensure that the Speedster hood tucks seamlessly under the clean edge of the bodywork.

The result is a car that looks as well as it goes, and it goes like %@!#.

Exterior

We have to say that the build quality and finish on this car, which is No.11 of just 25 Abingdon Edition cars, is just about as good as we’ve seen on any car that’s come through our portals here at HQ.

As far as we can see, the bodywork is entirely bereft of any flaws, nicks, deviations, ripples, dinks, dents or other aberrations except for those only visible through a powerful magnifying glass or microscope.

We like the way the flat, extended Speedster-style tail contrasts with the bespoke bonnet with its power bulge to create a silhouette that’s not quite like any other MGB Roadster out there. 

The panel gaps and shut-lines are laser sharp throughout. 

The chrome work is as bright and shiny as the top of the Chrysler building and has yet to be troubled by anything even remotely approaching foxing, tarnishing or pitting.

But it’s the quality of the paint job that really caught our attention.

The Glacier White paint (the original colour of the donor car) is thick, even, lustrous and untouched by any scratches, scuffs, stone chips or blemishes of any consequence. 

It is a quite superb example of the spray-painter’s arcane craft.

The wire wheels look fine, as do the matching Avon tyres.

So, too, do the car’s lights, lenses, badging and other exterior fixtures and fittings.

The bespoke, Speedster-style hood, you won’t be remotely surprised to hear, is beyond any reasonable criticism, goes up and down with a minimum of fuss and bother, and stows away neatly in the boot.

Interior

This car has only covered 7,509 miles from the time it left Frontline, so you’ll be looking in vain for evidence of ingrained patina or wear and tear.

What you will find is yet more proof that no-one does re-imagined MGs better than Frontline and you’ll see the evidence in everything you can see, feel, hear and touch.

The textural and aesthetic tone is set by the New England Saddle Brown leather, which is as warmly welcoming and inviting as a catcher’s mitt.

The seats are supportive (hand-shaped alloy buckets are the underpinnings) and comfortable, with the upholstery having just a few light and entirely reasonable creases here and there.

The black crackle finish on the dashboard and steering wheel boss is pretty much pristine and helps give a period feel to the interior.

Naturally, the Dark Charcoal grey carpets are by Wilton; obviously, they’re in very good condition; and, of course, they’re edged in Warm Charcoal Nappa leather. 

Everything is designed, crafted, stitched and finished to levels that would make a Savile Row tailor proud. Nothing is worn, broken, tired or faded.

The bespoke central storage cubby contains the ignition key slot.

The storage deck behind the seats is in fine fettle, as are the door cards and, well, everything really.

The lining of the hood, save for the odd mark earned during stowage and/or erection, is in first-class condition.

To the best of our knowledge, all buttons, dials, switches, knobs, gauges and levers do exactly as they’re told without deviation, hesitation or repetition.

The boot, which contains some tools and various covers and hoods, is as close to immaculate as a used boot can get. 

Are the boot’s internal wheel arches and fuel pipe wrapped in New England Saddle Brown leather?

Of course they are. 

Mechanical

The engine bay is full of very clean, very dry, very orderly Mazda engine that’s been optimally tweaked, fettled and tuned.

Everything appears to be in its right and proper place.

The car’s undersides are following exactly the same script in terms of condition and quality.

Absolutely nothing we’ve seen has given us any cause to tut, frown or otherwise question the car’s character or honesty.

History

This car has yet to pass the 8,000-mile mark so it doesn’t come with a wheelbarrow full of bills, press cuttings, photographs or letters.

What it does have, however, is a full service history showing that it’s been serviced and maintained throughout its life by Frontline themselves. 

Obviously, you can’t do any better than that.

It comes with its original build and specification sheets, a BMIHT certificate, a recent HPI report, full sets of keys and a V5C.

It also has an MoT certificate, with no advisories whatsoever, that’s valid until 24th September 2026.

Summary

Some people roll their eyes and start slowly shaking their heads from side to side when confronted with the notion of an MGB Roadster that cost its first owner nearer to £200,000 than £100,000.

They are, invariably, people who’ve never driven or experienced one of Frontline’s sublime automotive creations.

This particular example is about as good as they get and has the added advantage of a unique Speedster-style hood and accompanying silhouette.

We like it a great deal.
