Depends what you want it for. If it was a dream vehicle then id drop 10K on it no sweat, even higher. You could get a good short block off LXForums for probably 3K ish, put all the accessories off the blown motor on it and be laughing. Or even send the short block out for a rebuild, perfect time to add forged Pistons and a cam.
SRT Jeeps keep their value. Heck even if it's not a dream vehicle and it's just something to have abit of fun and then flip, 10K is still a good deal, . If it's as nice as you say then it's worth well over 20K once it's back up and running. Good for you if u can get it for 2K but be prepared to get laughed at or have the guy be insulted, that price is a dream
