My dad is looking at buying a luxury type sedan or coupe. Something that is an '02 or newer with less than 60k miles that he could get for around 25k. Gas mileage is somewhat important as is reliablility. The car isn't going to be modded and he's trying to avoid a "mid life crisis" car so keep that in mind. Already considering infiniti g35, lexus GS, and bmw 5 series. Any suggestions on what to buy or avoid are welcome
