Does the Lf. quarter look bondoish above the rear wheel? The reflection looks strange to me. https://miami.craigslist.org/brw/cto/d/fort-lauderdale-1968-buick-gs-california/6814364395.html
Gary if you look at the back bumper you see a scrape or a hole. Probably swiped down the side and they mudded it and skipped fixing the bumper. Beat em up on the price and that could be a decent driver.
