Mark, you could drop it into 'The car wash'. It's on the left as you come into Wilmslow from the A34 atlantic ford bypass, approx 20 metres before the lights. We subcontract some work to them from our Jag dealer.
Infact, if you give Warren a call - 07818 042919 (he owns it), you can get it all booked in. Because of your proximity they'll probably drop it back to you.
They used to clean my S2000 and are pretty good. Not to mention just around the corner and across the road from my local and the best tapas in Cheshire
Best bet for a proper job is one of the local mobile valeters like VIP or Pure Gold.
Fieldl I just realised where that pic of your car was taken, I occasionally park on that street (although I've found a much more convenient place to park now).
