Scale drawings were from a book, thought to have been written by H.G.Conway, and now out of print. Measurements closely correspond to those published in "Bugatti, Evolution of a style", by Paul Kestler, 1977. The ash frame was made to order by Bob Jones of Teal Cars (well known for their replica Type 35's etc.) Vintage Wings of Manchester built the aluminium body & wings. Dashboard, instruments, radiator cowl and grille were supplied by Projects of Distinction Ltd.

Suspension is by semi-elliptic springs & friction shock absorbers on the front; reversed quarter-elliptic springs with telescopic shock absorbers on the rear. Disk brakes were fitted to the front axle, for safety in modern traffic conditions. Drum brakes were fitted to the rear. Powered by a 145 h.p. Nissan straight six engine, it will climb hills effortlessly in top gear. Third gear takes the car to 70 mph, and fourth to a top speed of 80 mph, when head and shoulders feel close to parting company!
The original Type 50 Grand Sport was fitted with a 4.9 Litre 'straight 8' engine. Three of these engines were built for the Le Mans 24 hour race, and installed in experimental chassis of 10'3" wheelbase, 4" shorter than the T49, which was also introduced as a new model in the same year (1930). However, tyres and suspension couldn't handle the power. The straight 6 engine is smooth and powerful, has a catalyst fitted for unleaded fuel, and is much more suitable for modern motoring.

In 1989, a Sunday Times Magazine supplement "Quality Cars" published an interview with Richard L'anson (a Bugattiste) who speaks about building one-off Bugatti engines:
"With the men's machining skills and my 25 years of experience it ends up right. But it does cost at least £40,000 to make an engine." Ten years later, Tom Wheatcroft spent £1.6 million building a one-off Bugatti Royale, the engine for which cost £180,000 !
Tim Perry of TJP Classic Services installed the engine, wiring loom etc. Holden Vintage & Classic supplied the steering wheel, indicator arm, rear lamps, horn push, H.T. leads etc. The Complete Automobilist supplied door handles, locks etc. Nuneaton Fine Finishing, chromework and Star Engineering supplied the badge. Details include Bugatti replica foot pedals, wire wheels, Lucas P100 headlamps, turned aluminium dash with brass instruments, turned aluminium engine bay and plates, monogrammed EB radiator cap and gear knob, leather seats, bonnet and luggage straps and replica 1930 road fund licence. Approved and registered by the Ministry of Transport as a Bugatti in 1985, the car bears an appropriate period registration number.
