Why don't we all agree that, as TDI's go, we can assume the following
Cupra TDI = FR TDI (exept wheel design, some mirrors and 6 disc changer)
Styling, power and handling all pretty much the same
FR+, same power and handling, just "looks" like a Cupra R (with 17" rims), plus any extras SEAT had left over before the MkII came out
As Petrols go, well we have
Cupra, = simple styling, 16" rims, 180bhp, pretty quick
Cupra Facelift, = as above, but with 17" Starfish Alloys, Revised front and rear bumpers, white dials, still pretty quick
FR (petrol 180bhp),= as facelift Cupra, with the different wheels, mirrors etc.
Cupra R (210),= 18" rims, recaros, Big front and back bumpers, splitter, and most importantly a little quicker and firmer
Cupra R (225),= as 210 Cupra R pretty much, but again a little quicker
In simplified terms, I reckon thats it.
I'm happy to be corrected if people think I'm not quite right.
We should all be happy that we love these little spanish wonders
