Ground rules: No supercars, sports cars, or muscle cars allowed. It can have power, but only if it's a "luxury" feature rather than a performance one. Also, just for the heck of it, no cars that are currently on sale. It must be discontinued. Go.
For me, it was a bit of a toss-up between the Chrysler 300M and the Olds Aurora. I've discussed my love for the Aurora before, but ultimately the 300M won out because I'm a Mopar guy. I just love this thing. Apart from the slightly pinchy grille, the 300M looks fantastic. On paper it's good too. It's got a 255hp V6 going through a 4 speed manumatic, with a 0-60 time of 7.5 seconds, which is not bad for a big car. Did I mention it made both Motor Trend's Car of the Year and C&D's Ten Best in 1999?
