I wouLd like Seat a spanish car brand especial y the cupra one and fr edition they have the same platform of the golf or the sedans from VW

For the Seat you have to go to older Forza Motorsport titles (FM 4 I think). Today Seat and Skoda only give licenses to WRC Rally games (or their mother VW does).

There is a special car wishlist thread pinned on the top for your needs.
