This is Clarion K1 Attack Roadster, which has been built by a senior technical manager for a Mercedes-Benz dealership in Bristol – Oliver. K1 Attack Roadster is a true masterpiece and fulfils Oliver's dream to create a unique car.

The project started with an approach to Swindon-based mobile entertainment specialists - Clarion, who Oliver suggested might like to showcase its award-winning audio, multimedia and satellite navigation equipment in his project.

After 4 000 human hours over 3 years and £70 000 of Olivers hard-earned cash and savings – the unique K1 Attack sportscar is ready to catch the attention of everybody, who sees it.

Starting with a basic chassis, some body panels and a variety of components, delivered in a box from the Slovakian factory in 2006, Oliver set to in his garage, creating and building his dream car in stages.

"I have actually assembled the car four times since starting the project", commented Oliver.

"I had an original concept firmly in mind, and the design and specification evolved as I went along by building the car, checking the fit of every new component, dis-assembling, making modifications and so on, until I was happy with every element.", he added.

All parts of the car are custom made, specially to match Oliver taste. The parts list is huge and includes linear actuators and mechanisms for opening the driver and passenger doors by remote control, carbon fibre bodywork and interior detailing, colour-coded cabling, polished hoses and pipework, chromed suspension and a full bespoke leather/Alcantara cockpit, detailed with exquisite design and styling touches.

"For example, I chose Asanti wheels from the USA, at £2,000 each, because they are just the greatest. I spent many thousands of pounds more on the composite bodywork styling, hand-crafted seats and interior, suspension, lighting, designing and engineering a right-hand drive conversion, even chroming hundreds of nuts and bolts…the list is endless.", explained Oliver.

The car is powered b Honda Civic Type R 2.0 litre 4-cylinder engine delivering 250bhp and combined with 6-speed manual gearbox. Furthermore, the car has race-bred suspension and formidable Brembo braking.

Amidst all the attention, Oliver is frequently asked what he'll do now the car is finished. "I've actually been offered a lot of money to sell it but I plan to enjoy it for a year or so, and after that? Well, building a speedboat from scratch could be fun," he mused, suggesting this isn't the last we'll hear of the West Country wizard.
