An 02 with only 36k on it and an LSE should go for around 17 I would think. Maybe more. I got my 02 LS8 with 55k on it for 13.5, but the place was asking 15.9 when they first got it. They'd had the car for so long they were just desperate to sell it so I got a better deal. Id say at least 17 for yours. Considering most dealers would probably only give you 12 or so for it on trade, then try to sell it for 19 or 20.
