as said its not worth making a rep, prices are circa

decent puma 1500
engine 1500
interior 1000

new parts:
pannels 2000 or fibreglss reps 1000
suspension wishbones etc 2000
paint 1000
wheels & tyres 1000

obv you could get alot of the stuff second hand but it rarely shows up in decent condition but its still a large price, just get a genuine frp, trust me it will make you smile everytime you drive it :P
