[Detox]

Ok so here is the deal. My bro is done w/ college (WVU) and going to be working down in Florida. He is in the market for a car and I have suggested to him so far a Altima SE-R, Mazdaspeed6, and Acura TSX and TL. I just wanted some input from you as to what you thought would be a good purchase, the criteria are as follows.
1. Relatively new, from 2005 on up
2. FWD is preferred, although RWD and 4wd are options, Keep in mind Florida weather
3. Under 30K miles
4. Sedan
5. He prefers one w/ a Navi, but does not HAVE to have one
6. Around 25 grand
7. He's going to be working w/ a landscape architecture firm. Occasionally will be transporting people, but he's single now. Gas mileage is a factor but he says the fun to drive factor outweighs the mileage issue

Thanks for the input, he's worked really hard and deserves a great car. He initially wanted a G35, but I'm trying to see what else is out there.
