2005 Chevrolet Blazer For Sale by Owner in Uniondale, NY

I have available for sale a 2005 Chevrolet Trailblazer LT Extended Truck with third row seating. Just clicked over 125k miles. Great looking vehicle, just a few minor cosmetic blemishes and quirks. I had recently been looking to trade or sell it, but at the end of May it had an engine problem develop suddenly and there is a clanging noise coming from engine, yet the truck still drives. I am not sure what it is...maybe pistons, valves, I don't know. I already had a second vehicle I recently bought that was going to be my car when I eventually sold the Trailblazer, but it became necessary with this recent problem. I don't think I even want to get into taking the Trailblazer to get fixed. I had a family of 8, but no longer needed the bigger truck as I rarely ever have more than 3 people in truck at a time. It was a daily driver and I used for personal as well as a business truck moving merchandise to shows.
