Brookspeed are delighted to present this stunning Gardner Douglas GD427 Cobra, beautifully finished in Dark Blue with classic Old English White Le Mans stripes. Registered in 2002, this exceptional example benefits from Historic Vehicle status, making it road tax exempt, and represents an outstanding opportunity to acquire one of the finest Cobra recreations available today.
Gardner Douglas has long been regarded as one of the UK's premier Cobra manufacturers, renowned for producing beautifully engineered cars that combine authentic styling with outstanding build quality and exceptional driving dynamics. The GD427 is widely considered one of the finest Cobra recreations ever produced, offering the perfect balance of classic 1960s styling with modern engineering, reliability and exhilarating performance.
At its heart sits a formidable 5.7-litre (350ci) Chevrolet V8, paired with the highly desirable Tremec 5-speed manual gearbox, delivering effortless performance, immense torque and the unmistakable soundtrack that only a large-capacity American V8 can provide.
In 2020, the engine benefited from a carefully selected programme of performance upgrades, further enhancing both power delivery and drivability. The work included the installation of an Edelbrock RPM Performance Package, incorporating a new 7102 performance camshaft, roller timing chain set, Torker II inlet manifold, Edelbrock 1405 600 CFM carburettor, and a high-performance aluminium water pump. Following completion of the upgrades, the car was professionally set up and tested on a rolling road, where it produced an impressive 385.2 BHP. The result is a wonderfully responsive V8 with effortless torque and exhilarating performance whilst retaining excellent road manners.
The engine bay is every bit as impressive as the exterior, beautifully detailed with Edelbrock rocker covers, chrome alternator, chrome crank and water pump pulleys, polished air cleaner, silicone hoses and a host of carefully finished components, reflecting the quality of the build and the attention to detail throughout.
Finished in the timeless combination of Dark Blue with Old English White Le Mans stripes, the exterior perfectly captures the spirit of the original Cobra. Chrome front and rear bumpers, full Cobra badging, chrome mirrors, stainless steel wipers, twin chrome three-leg rollover hoops and classic 16-inch Halibrand alloy wheels complete the unmistakable appearance.
Inside, the cockpit remains true to the traditional Cobra theme, featuring Smiths instruments, a Momo steering wheel, Cobra gear lever, Willans harnesses, heater and a discreet Retro DAB radio with USB and AUX connectivity, successfully blending period character with modern convenience.
Mechanically, this GD427 has clearly been maintained to a very high standard throughout its life. In 2017, both the engine and gearbox were removed to replace various seals, while an immobiliser was installed in 2016 for added security and insurance purposes.
Accompanying the vehicle is an extensive history and build file, including build documentation, invoices, previous MOT certificates, dyno sheets, spare keys and a wealth of paperwork documenting the car's build, maintenance and performance upgrades.
The car is supplied complete with its hood and side screens, allowing enjoyable open-top motoring whilst retaining practicality should the weather change.

- Iād just like to say thank you to Simon and the team at Brookspeed, for making my recent purchase a fantastic experience. It was an absolute pleasure dealing with them and their amazing business. Their facilities are second to none and well worth the trip down from Bristol. Simon provided a professional and personal service throughout the whole purchasing process. So I would highly recommend Brookspeed and will be definitely using them again in the future.Thank you all ????
- What can I say Brookspeed apart from a huge huge thank you, especially to Phil in the workshop for rebuilding my Cayenne's engine so impressively but mostly to Simon King, the MD who went over and above on the attention to detail to ensure my car was safely delivered by the AA on Boxing Day, opening up especially to take delivery, for explaining all the work so I completely understood everything that needed to be done and was done with such care and expertise (see ref to Phil!), for ensuring the...

- Second time I've used Brookspeed to fix my 987 Cayman and both times they've been great. The new location is impressive, and I was able to work on my laptop in the (very grand) waiting room whilst my car was being fixed (new window regulator). Their technicians know their stuff when it comes to Porsche, and the cost was exactly as quoted, so I was a happy customer. Friendly staff too, who kept me supplied with tea and coffee. Would recommend.
- Fiting of my Porsche Sports exhaust and tequipment sports suspension was done expertly and very promptly. My 981 Cayman S now sounds and drives even better and remains a true Porsche so thanks to Stuart, Phil and Bethan and the rest of the team who are friendly and approachable so will make make me a return customer.Thanks Brookspeed!
- After many months of deliberation of looking at wheels - lowering - and suspension and many transporter forums l went to these guys for help as l was finding it all a nightmare.I had a meeting with Phil and Alex and went through the dos and don'ts and they were so helpful and certainly knew what they were talking about. So, l booked in for a service - MOT - and to change of suspension and slightly larger wheels. They and the mechanics made a really brilliant job the van looks and drives superbly... Read More
- Absolutely fantastic service. The mechatronic unit on my TT went and they were able to fix it at a much lower cost than expected and it was quicker than we thought. They talked us through every step and I felt nothing other than confidence throughout the whole experience. A special shout out to Phil who was so helpful and kind. I will be using them again!
- Following two days travelling from Spain, we arrived in Eastleigh with a serious engine problem. We found Brookspeed through Google search and arrived on their doorstep as they opened the following morning.Phil, Mike & Tom were absolutely fantastic. They did an initial inspection immediately and confirmed that we had a serious problem. Phil kindly took us to the local car hire centre and within 3 hours they had diagnosed a component failure and given us an estimate for the repairs. They kept... Read More
- Professional and Friendly from first contact throughout. Had coilovers installed by the guys, Tom asked me how I wanted it to sit and gave me lots of advice, and its fair to say I got exactly that! the van feels and looks amazing! I couldn't be happier with the service I received and will definitely be using them from now on! ????
