There wasn't enough influential European used cars though. As for the American cars, well without being confrontational, the abilities of US cars are far behind EU and Nippon vehicles. Hence fewer to choose from that are worthy of being raced.
I agree in part with that. The US selection has too few race cars to choose from, and here they are:
Chapparal 2D and 2J, Chvey Camaro LM Race Car, Chevy Corvette Z06 Race Car (C2), Chevy Corvetter C5R, Dodge Viper GTS-R Team ORECA, Ford Escort Rally Car, Ford Focus Rally Car, Ford GT LM Race Car, Ford GT LM Race Car Spec II, Ford GT40 Race Car, Ford RS200 Rally Car, Panoz Esparante GTR-1 Race Car (13 total, 11 without rallies)
while the European selection of race cars is:
Gillet Vertigo Race Car, Citroen Xsara Rally Car, Pescy Courage C60/PEUGEOT Race car, Pescy C60 Judd Race car, Renault 5 Maxi Turbo Rally Car, Renault Clio Sport Trophy Race Car, Audi Abt TT-R Touring Car, Audi A4 Touring Car, Audi R8 Race Car, BMW 320i Touring Car, BMW M3 GTR Race Car, BMW McLaren F1 GTR Race Car, BMW V12 LMR Race Car, Mercedes 190 E 2.5-16 Evo II Touring Car, Mercedes CLK-GTR Race Car, Sauber Mercedes C9 Race Car, Mercedes CLK DTM, Opel/Vauxhall Astra Touring Car, Opel/Vauxhall Calibra Touring Car, VW Lupo Cup Car, VW Lupo GTI Cup Car, VW New Beetle Cup Car, Alfa Romeo 155 2.5 V6 TI Race Car, Lancia Delta HF Integrale Rally Car, Lancia Delta S4 Rally Car, Lancia STRATOS Rally Car, Pagani Zonda LM Race Car, Bentley Speed 8 Race Car, Jaguar XJ220 LM Race Car, Lister Storm V12 Race Car, Lotus Motor Sport Elise (31 total, 26 without rallies.
As you see, Europe has more than twice as many race cars in the game, and 13 times as many rally cars in the game than the USA. I didn't bother with road cars or Japanese cars because I would have been here all day.
EDIT: How can you say that US cars are "far behind the abilities of EU and Nippon vehicles"? American automobile are just as capable as European and Japanese cars and trucks. I don't know what you are referring to, but if its power, the Viper has plenty for everyone. If it's cornering, the Corvette Z06 can do as well as any European coupe or Japanese Coupe. The Corvette can be driven day to day as well, so it has great reliability. The 300C is an excellent sedan that has great power if you bump it up to the SRT8. In short, you are wrong that American cars are inferior to European cars and Japanese cars.
