What used Sport Sedan should I buy? I am looking for a sport sedan and I'm having a hard time with all the options out there. On my list are a Q50 Red Sport, S6, Charger 392, CTS-V, V-Sport. All used. My main concern I've been unable to effectively research is depreciation because I drive a lot for work (900-1,000 miles a week). Looking to spend ~$30,000. Any advice is appreciated. To be clear: no interest in a slower more frugal vehicle, not trying to save necessarily just trying to lose less. I'm aware there are more fiscally responsible option but I want something fun and I something nicer is important for what I do for a living.

I require a car with 4 doors. I do need room for cargo or passengers.
My price range is ~30,000.
This car will primarily be used for a daily driver and for work commuting.
Minimum # of seats: 4
Must haves (mpg/fast/high seating position/tech): Fast, fun to drive, comfortable, media bluetooth
