Rhys-

I'm quite sure my car from the fresh build didn't cost over 4k and it wasn't a bad motor tbh

Seam welded shell re panelled and full resprayed
Polycarb windows
40k xe engine and F18 box with Quaife LSD
Solid mounts, GTE shafts, new cv's and kwik rak
16" Compomotive Mo's
Coilovers with concentric alloy mounts
Reyland Brake conversion
Sparco buckets and harnesses
WON nitrous kit

8.55 lap of the ring
13.051 1/4 mile

cheap considering it was 100% reliable, very quick for a stock engine and excellent mpg.
