Given their Caterham track record I contacted Dreadnaught recently about servicing my 620R. Had to endure a big story about how Caterham had dumped them and despite all their past of working on the cars they couldn't do so any more, because the factory wouldn't support them they didn't feel Confident or something along those lines. Bizarre was putting it politely. Basically, the guy didn't want to service my car or want the work! Total waste of a phone call. I can highly recommend Craig Moncreif, Craig has worked on my Exige for years, top bloke. My 620 is going there week after next for Service and MOT.
