not a bad price if you are dropping off a shell and boxes full of bits, what's your total spend going to be including his labour and buying all the parts and shell etc??
Might be cheaper to buy one ready done, ebay is full of S2's £1500 should see you in a tidy one with 180bhp with a bit of searching, then when your done with it, flog it on, that is if you ever go back!!!
