As for 4-door cars that are manual and AWD with ability to modify, I'd go for Mitsubishi Lancer Evolution hands-down. I like the way they drive way more than the Subaru Impreza, although on paper they're very similar.
A coupe is a bit more difficult.
Mitsubishi Eclipse GSX / Eagle Talon TSI are both turbo/awd coupes. Neat cars, but they're a bit old now.
If you were in Japan, Nissan Skyline GT-R fits the bill perfectly - and it's a coupe.
Here's my car.
You really need to specify your price point and whether you're OK with buying a used car. I would definitely get a used car if I were you.
