S2 has so many nice points coming from an S1... How many thing are adaptable and worth to an S1?

 

Look unless you are wanting to purchase ASSEMBLIES of from say a Wreckers or Junkyard, say like a pair of FRONT SEATs or set of Front and Rear Seats as S2's are way much better looking, better quality, don't go for the Recaro as I doubt you will find any that has not got the side bollster flattened from use.

As for parts, well again not a lot which is the same on the Front of car, front Bumper, Grille, Headlamp and Parkers are all different?
