I purchased a Excursion from a body shop. It was advertised on bay as everything works with one exception the reverse sensors. Upon getting it to Indianapolis I found that the engine controller did not work. The air bag passenger side was missing and the drivers bag was incorrect for the vehicle. The light on the dash that would indicate the airbags were not workin was removed perhaps to cover up the bags were missing and not correct for the vehicle. The wire harness was missing for some of the rear of the vehicle. The rear brakes were warped. The ad was written by a gentleman who had not seen the vehicle. The seller offered to do nothing. The vehicle might have been great but you can see the problem. I have over four thousand in repairs and still going up.
