WTB: Grown-up Car

[Levey]

So the 2002 Camaro is a great car. Tons of fun, over 400 hp, and the roof is see through and removable. What's not to love? Well, it gets 14 mpg on my 14 mile commute (do the math), it's 11 years old and kind of clunky, and most of all it does not portray the fact that I have a real job that pays pretty well. So I have been looking around trying to decide what will replace it. I am all over the map, so have not pulled the trigger yet. When I made the move from the 04 RX8 to the Camaro, I vowed to myself to never own anything without a V8 ever again. Ehhhh, maybe I can break my rule. So i'm looking to spend up to $35k. If I top out my budget, whatever I get better be pretty much new. Otherwise, decently low mileage is acceptable. Here how my mind has been working thus far. My focus is on modern interior, non-lame exterior, overall cost of vehicle. Power is a plus, but wimpyness could be justified (ct200h?)

Audi A5: Gorgeous, AWD, 27mpg highway, not too expensive insurance, luxurious, sporty, but maintenance would suck.
BMW 335i: Power, luxury, but still the high maintenance costs.
Lexus ct200h: Massive amount of technology inside, unique looking, 40+mpg, but 98 freaking hp. Would this be stupid and boring in 8 days?
08+ Corvette: Because Corvette, but might miss the backseat, and insurance is insane.
12+ Mercedes C300: Because I could own an almost new Mercedes in my price range. But that's the only reason.
SUV: a jet ski may be purchased in the next couple of years since I live at the beach now. This opens a whole other string of possibilities.

I'm open to taking a lashing if the above choices all suck. Let's hear it.
