A truck has been on sale for 365 days is it bad

It could be. Or it could have a vehicle history report that shows it was in an accident or bought back as a Lemon. It could be an unpopular color. It could have high mileage or be overpriced. There are many reasons why a certain vehicle doesn't sell quickly. My 93 Caprice, which was brand new when I bought it, sat on the lot for 4 months before I bought it. I had the car for 19 years and it was a perfectly good car. If you're interested in it, buy a vehicle history report such as carfax and if that looks good go check it out. If you're not vehicle savvy have a trusted mechanic or a professional inspection company check it out for you. If you like the look of the vehicle it's worth a look! Hope that helps! Jim
