6-spd, leather interior, 4dr, 3.5L v6

or a ford fusion SHO

 

xB2 Everone has a euro-lux sedan for business, you'll definately stand out with it.

Was going to say the same thing about grabbing used vs. new, haven't owned a certified used before but from what I understand the ones from leases are usually pretty well taken care of.

Give the Genesis a look, or (and I'm probably going to be laughed at / flamed) if you can wait another year the 2010 Ford Taurus. The current Fusion isn't bad either, and you could probably get domestic at a good price if it's not a Mustang. My one sugestion would be to get a manual or AWD if you can find it, my experience with Ford's FWD automatics have not been good (they were Mazda designs), but the other trans options seem stable. Volvo really helped with AWD.
