I guess I better chime in.....
The 3/S is a great car. I'm probably one of the few people here who have driven every flavor of 3/Ses and DSMs.
If you are getting a killer deal on a non-turbo 3/S and you are going to use it as a daily driver, then go for it. If you have any kind of power bug, just find a twin turbo model now and save yourself the time.
And Josh is right, with simple mods a monkey can do, a 3/S TT can do high 12s in the 1/4 mile. And that will spank most of the DSMs on the board. Plus they are still super reliable at that power level.
Are they heavy, sure they are. But that is what more horsepower is for.
have fun,
