Sure the early 3rd gens left a lot to be desired, but 85 and after on both the iroc-z and T/A had a look that was great. Of course its either a love it or hate it, but in time that car will be a very collectible car. I think Gm needs to not emulate each generation, but take a little of each gen's trademark styling to go along with new cues. That's what made the 1st- 4th gen evolutionary.
Of course I love all the gens so I am a little biased.
