The only real reason you would get an FR over a
Cupra is cost to buy.
Cupra is better or same as FR in pretty much everything except slightly crashier ride and marginally worse MPG. You can quite easily match performance of standard
Cupra with a mildly modded FR, but if you were to mod the
Cupra you would out do the FR obviously. I've got an FR and love it but wish I had a
Cupra as it would be a better starting block, but suppose getting a car like an FR when your 19 is still good!
