An opinion only:
The interior says it's a Formula which would be a V6, not a 4-cylinder. It has the 120 MPH speedometer cluster and the auxiliary gauges. If that's the case, the deck lid has been replaced with a non-spoiler lid and the car has been repainted at some time, though the rear fascia still has the VIN sticker behind the license plate. I'm not sure what those discolored stripes on the deck lid are about. I can't tell if it has quad exhausts or not. The picture is too dark. With the other issues like the front fascia and the badly worn interior, I'd offer $1800, max.
If it is a 4-cylinder, I'd not go more than $1200.
Just my opinion.
