um... quick question. so is it a 90-91 or a 92-93? the front end is that of a 90-91, and the trunk/tail is that of a 92-93.

i was looking for the automatic seat-belt with your interior pic, which would indicate it's 90-91.

in any case, you may want to find out if the car has been in an accident or not, or at least anything that could explain the different front/tail ends.

other than that, it's a clean 4th gen.
