1988 Cheverolet Monte Carlo SS 85k miles Black/Tan 355 lots of new parts

Description for Chevrolet Monte Carlo 1988

Selling my 1988 Monte Carlo SS. It needs a little work to get it back on the road. I've owned this car for 16 years now. I started this project before I was married and before kids. So as the story goes, I'm conceding and putting it up for sale. The body has approximately 88k on it. All of the new parts have less than 1 mile on them as I never plated this car. It is a real SS. Original color is all black with the gold sticker package. Tan interior in great shape, just needing a cleaning. No rust. Body in great shape. I have all the pieces for the car, like the SS horn missing from the picture on the steering wheel.

Before I owned it, the car was stolen. The column was broken. I bought the piece to fix it but have not fixed it yet. I'm available on the weekends and some evenings to show the car. I added up the receipts years ago and did almost all of this work myself, it still came to over $12k.Thanks for looking
Car starts but backfires and dies. I think it's just timing or carb needs adjusting.
Power windows and locks need connecting. I put new/used doors on it recently.
No major rust. Car has been indoors all these years except the past year. Passenger door was scraped/dented by my daughter in a golf cart, will get pictures soon.
Will get additional pictures up asap.
