This is the K1 Attack roadster built by 26 year old Oliver Ashely, a senior technical manager at a Mercedes dealer in Bristol. The K1 Attack roadster was born of a small Slovakian producer, and involved no less than 4,000 hours of work and 70,000 GBP, not to mention lots and lots of skills and talent.
Powering the K1 Attack roadster is a remapped and tuned Honda Civic type R sourced 2.0-litre engine that develops 246 bhp and which also uses the Honda type R six-speed manual gearbox. Some custom work in the engine department involves light weight racing batteries, HKS inlet air intakes, colour coded and polished hoses and pipes, and a supercharger conversion is also scheduled to be fitted in 2010.
As K1 Attack roadster uses a tubular steel chassis with a composite body covered in white pearl plus various carbon fiber elements.  As far as suspension Oliver has chosen a set of Sporteing adjustable coil-overs with custom springs.
At the interior the K1 Attack roadster features Clarion’s award-winning audio, multimedia and satellite navigation equipment.

Clarion press release :
To some, a car is simply functional, to others a passion, but to 26-year old Oliver Ashley, four-wheel fever knows no bounds.
Since 2007 Oliver, a senior technical manager for a Mercedes-Benz dealership in Bristol, has been building a car from the ground up, forsaking a normal social life to fulfil his dream of creating a truly unique automotive masterpiece.
The K1 Attack roadster, on which Oliver’s car is based, is born of a small Slovakian producer, and has been on the hardcore enthusiast’s radar across the globe since the first cars appeared some years back. Progress to market has been slow, which prompted Oliver to take matters into his own hands.
It 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.
Over three years later, after 4,000 hours of spare time toil, patience, immense skill, and an almost obsessive drive for perfection – not to mention £70,000 of his hard-earned cash and savings – Oliver’s unique K1 Attack sportscar is wowing crowds at shows across the country.
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”, said 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.”
Oliver’s parts list, created as the build progressed, included a whole host of one-off items specially produced for the car – which he designed and had made, all echoing his fanatical desire for individuality and quality. These include linear actuators and mechanisms for opening the driver & 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.
But as Oliver explains, attention to detail doesn’t come cheap: “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.”
Along with Clarion, which has supported Oliver from the outset with a dashboard delight of  of state-of-the-art audio and DVD, amplifiers, ‘speakers, hard drive navigation, and a rear reversing camera system, other major brands have assisted in the build, including MOMO, which dipped into its treasure chest of interior styling products to add Italian flair to Oliver’s creation, and Yokohama, whose  legendary high-performance tyres now grace the car.
With a 250bhp Honda Civic Type R 2.0 litre 4-cylinder engine and six-speed manual gearbox installed midships, ultra taut race-bred suspension and formidable Brembo braking, the car’s performance is more than a match for its stunning looks, which are capped with a sumptuous Lamborghini pearl white paint finish.
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.
