Hmmm: If money was no object, and my last commute was long boring highway miles, perhaps a Mercedes SL55AMG. 500 hp, V10 goodness, does everything well, great soundsystem, comfortable, a real trunk, incredible seats. I have 2 friends that own them, and last time I was in one of them, I had to decide if I wanted Shiatsu or swedish massage in my airconditioned seats.
But with a price as factor, I think my old 4 Runner fit the tab nicely. Comfortable, simple, great heater, poweful a/c, roomy enough haul anything on the way home, high ground clearance to wade thru flooded roads, part time 4WD, great in bad weather, ridiculously reliable, and decent gas mileage. The only two downside is 1. it's not sporty, but with the commute, that's not a priority, and 2. if I want a heated seat, I need to eat Mexican food th night before.
