Thanks Guys, I am new back to Caterhams (I had I think No 12 with a Twin Cam originally which is now residing in Japan) and I had forgotten the enduring way they love you, being of advanced age I wanted to draw on your experience before I spent money and made mistakes. I do appreciate all your help and advice, I fell in love with them again this morning watching the front mudguards dancing and hearing the exhaust pop as I drove through my part of the New Forrest:- 2010 Sima SV 18,500 miles I bought it from a Caterham dealer but "sold as seen" so I'm not at all worried about doing some minor bits of work. After making sure it's reliable (brake fluid etc as Tom advises) I plan to put a TTV lightened flywheel in, a heat exchanger (oil/water) run it for the summer then look at upgrading it to 140/150bhp and nickle plate the front suspension. Oh I should also add that the brake warning light(s) are flashing whatever that means so I will have to RTFM? Tom, I am in East Dorset bordering on Hampshire
