Cougar - this car handles like a stripped down Ford Contour, which is what the car is based off of. The four cylinder was extremely underpowered and the V6 was lacking, especially considering the size of the motor. Pre-turbo I could smoke any one modern Cougar on the road.
Celica GT - very snappy steering, excellent power for a four cyl. My major complaint is Toyota's desire to place all availiable horsepower into the upper RPM bands - you have to really rev that sucker. Ride is choppy and very low in comparison to a P5.
RSX - I think they handle just as well by compare. Horsepower wise any RSX would beat a P5 hands down - not just an Type S. Five speed manual shifts awesome.
V6 Mustang - Heavy, ugly, boxy, cramped, out of date. They'll win drag races against you, but in all seriousness who cares? They'll ride on the same 1978 redesign frame that the car started with.
Focus - recall city, baby!!! Slow, very slow, with handling you either love or hate. Poor seats.
