Edmunds Value is $15,000 for that car with that many miles and trim. KBBs would be higher probably 17k there.
Friend and I went car shopping this weekend, he's looking for a better car, I saw about 3 Legends for sale, all were 91-93 Legend Sedans (TypeI, NON-GS). One had 137k, had dings on it on the front, scratched paint, asking was $9,999. Second was a 128k, good condition, leather worn, $10,700, lastly there was one with 146k on it Good Leather, bad paint chipped, $11,200.
I got my 94GS Auto, in very good condition for $7200. BUT it has 133k on the odometer, and didn't have the "GS" rims, or BOSE CD player.
So YES, I would consider that a good deal. Of course, it wont hurt to try to knock it down half a grand or a grand
GO GET THAT CAR!
Get out there RIGHT AWAY. Drive her. If she is un-modified (sorry my modifying brothers) buy her. She should drive straight with no hands on the wheel, shift like polished glass, and run quiet. If you like the color, for that kind of price, you can stand a clutch or some other medium to light work. You are darn lucky you are 5KKm away...I'd be after her.
