Very nice... it looks like a 'little old lady's car' find with those running boards. :-D
More photos here in case the ad is dropped

One thing though, if it were completely factory, the grill and door handles should match chrome/chrome or black/black... that appears to be an 88+ grill?
The photo under the hood looks good, no sign of damage from a collision, perhaps the owner just liked the later model grill better but I'd inspect that area well if I was considering purchasing it.

1988 1989
Considering that window shade thing, someone was probably simply in the process of customizing it with the later grill.
