My family lost our great grandma so we are taking a 10 hour road trip next week to pay respects. My dad has never played games but really enjoys cars. We go to La Mans and GT races locally, he's been a car dealer his entire life, he has owned an unacceptable amount of valuable cars over his lifetime. He's always knocked me for gaming, but I'm going to help drive. I want to get a game that will be my best and maybe only attempt to show him some nerd fun he can play a bit while I drive. I'm thinking Forza 4 or 5? Other recommends or is one of these my best bet? Looking for something that looks good and runs smoothly. If there's anything with retro cars like 60s-70s Porsches, Mustangs, Camaros he'd love that I think! Edit: he likes building/restoring cars too, so if anything has stuff where you can drop engines or change wheels on he'd like that. None of that tuner stuff though, prefer something with MOPAR/classic American muscle. If I'm between Forza 4 or 5 which is the better choice?
