My Options with my Current 2008 X5

[kthankzbye]

Hi Guys, I've been having a bit of buyers remorse with the X5 3.0si. I love the car but I don't think it fits me/fast enough, not sure, still battling it inside. I realized I might be the youngest person on this forum that owns a X5 (25 single, not married, just gf's) by judging from that age and occupation thread. (Besides that 18 year old whose mom just bought him a X5M). I think I need a faster car.

The reason I got the X5 was because of winter conditions in NYC but I realized that it snows only like from Dec-Jan and I can always take out my old car which served me fine.

Now, my options are either are:
1) Trade it in for a 2008 535xi, I hope I don't loose too much on the trade.
- Another question is: I still owe about 13k on the SUV, did anyone ever trade in while still owe money on the vehicle?

2) Keep it while not happy driving it and finish paying it off and then get a CPO 2012 335i (Since I already got the X5 and I finish paying it off in 2015).

3) Trade in for a CPO 2008 4.8i hoping not to pay too much of the difference.


Or any other recommendations? I'm hoping not to lose too much on it, If I have to loose more than 3k I would just keep it and use it on 20" rims and aerokit.
It's a Silver CPO 2008 X5 3.0si with Tech, Prem., 4-zone-Rear Climate, Prem. sound and 42500 miles.

Please don't bash me, I just need people's opinions and I value everyones comments. Thanks!
