difference between PD130 sport and PD130 FR is obv the FR styling like badges, wheels, logo and rear lights etc. but main difference is sport has longer gearing, personally I prefer short gearing in the diesel as it feels more eager and you're always 500rpm higher so always at the magical 2krpm
I think there are ALOT of differences between PD100 though, internals? clutch? brakes, turbo... guess same intercooler, but don't have much experience with the 100 :/
