Mitsubishi Evo 6 Tommi Makinen Edition Subaru Impreza P1 Toyota Celica GT Four Ford Escort RS Cosworth
I went for the Evo 6, partly because I find the lack of rear doors on the P1 weirdly annoying. And my dad had a 6 and an 8 FQ-320 so I'm biased.
I'd go for the Toyota Celica GT Four of those, simply because I'm not an admirer of cars with over the top body kits as featured on the other three.
All 4 cars pictured are 100% factory standard (the Celica looks like it might have non standard alloys however)
