I knew full well going to Facebook to ask for advice could be dicey. My wife and I had had our fill of mechanic bills and were in the market for a new (used) vehicle. Searching online for low-mileage, well-maintained cars in our price range was proving difficult, but I thought I'd found a good lead. The car was about 15 years old but appeared to have barely been driven by its one owner. It was in great shape and seemed like a steal. There was only one problem. It was a BMW.
