I'm screwed

Sigs

I am new here.. I miss my old "Myspecv.com" community very much as it was a very useful and friendly car environment. Either way, my name is Josh. Get to know me. I'd like to post here more, but since I don't own a 370z [yet] I feel I don't have much to contribute to the community.

Okay.. back on topic. I've recently had some problems with my '02 Spec V. I thought everything was taken care of and getting back on track... well I was wrong. After checking the oil today, it seems like there are only 2 quarts remaining (full tank is 4.2 I believe) I'm not leaking.. and somehow that much oil has disappeared in LESS than 3 weeks and 600 miles. I still owe a substantial amount on the vehicle as I've only had it for 27/72 month loan x_x.. I'm pretty sure fixing it going to run me at least 2-4k$ which is almost a VQ engine swap. Any advice on what I should do here.. I'm really down about this.
