As one of the UK’s leading restorers of luxury classic cars, we come across all sorts of common problems that require the attention of our specialist engineers.

At KWE our aim has always been to ensure our customers receive a ‘better than new’ restoration service for their Jaguar XJS, XJ, XK and Aston Martin DB7 vehicles. So, we believe it’s important to share information that will ensure these vehicles maintain their reliability and roadworthiness.

We’ve noticed an increase in the number of classic cars being delivered to us for restoration with fuel system failures. Here we offer 7 preventative tips that will keep your vehicle in good condition and help avoid expensive remedial repairs.
