there all ap1 chasis code, but received a facelift of the exterior from 04, then 06 they changed the engine to dbw and the seats and rims (ap2v1,v2,v3) etc
I rkn its a good price, but why would you ask after your bought the car and not before... even if we tell you, it wouldnt really change the fact that you bought it already
if i was you, i would purchase a genuine mugen hardtop in FRP for the similar price as the CF one made in china from carbon plus.
Do it once, do it right they say.
But thats just my personal...
