Well I saw this post and i know it is old but as I im currently living in mexico I may answer any doubt on you on these brands SEAT (spain) Peugeot (France) Renault (france)
Seat is the middle range between VW and Audi they have Audi engines, bases, design, driving, quality but, with the price of VW. They are perfect, they are nice to drive, fast, cheap
Peugeot is a french brand with agreements with Mini and BMW in which They have mini-BMW engines and some innovations like Heads up display and those cars are also cheap.
Renault is the OWNER of Nissan The nissan Rouge is selled in mexico but theres also the renault koleos which is more luxurious and well designed.
The Ibiza is mostly like the Ford Fiesta but with no saloon version from 2010 and on
peugeot 207 is similiar but is about to be changed in mexico from brazilian version (crappy nobody buys it) to the real french version (appears to be nice)
