Enzo vs Corvette ZR1? Enzo would probably win (It's my preferred Tier 6 car)

Lambo VS V12 Zagato? I use the Zagato and statistically, it's better. It's also a hell of a lot more responsive and can beat several of the Tier 5 cars' times on occassion...

The Tesla Roadster is a much better buy than the DMC-12; the Tesla is basically an upgraded version of the DeLorean.

At the end of the game (the Championship race in Cup 13), the AIs were half-decently competitive, but you could easily beat them if you didn't wreck at all (which was fairly easy to do).

In terms of upgrading, the tracks were designed for speed of over 300+ MPH. Tier 1 cars were completely useless at tackling any track, and you normally got the best racing from anything over Tier 2 cars. If all the cars were pre-upgraded and balanced, then upgrading would not be necessary (although the cars still had to be fast enough for good racing and driver skill to become a factor).
