You can view other modules to verify mileage. When they set back an odometer it only changes the cluster module. BCM TCM ABS ECM can record mileage as well. Its foolish not to have a vehicle purchase inspected by a QUALIFIED inspector.
a family friend's son went to Jail for this in the early 80s when he was a Ford Dealer associate at McGovern Ford in Saugus where my mom bought her 1982 Mustang GT Coupe the 1983 weren't out yet on her birthday so she bought an 82 with 5 speed manual transmission though it had 157 Horsepower from a 5 L or 307 cubic in V8 engine while the upcoming 2025 iteration of the same car is expected to have 800 hp from a supercharged 5.2 l or 320 Cubic In V8 engine
Just use your instincts. If a deal is too good to be true, walk away. If a car has lower mileage than it should, walk away. If paint or interior show signs of higher mileage walk away. If a car is being sold within a short time after it's last sale, walk away.
