Over 275,000 miles on my '96 Mustang 6 cylinder and still going strong. Bought it used in '98 with 29,000 and have driven 135 miles daily round trip to work. The manual transmission went out at 185k and then the heater core started leaking at 225k. After they replaced the transmission, the speedometer cable burned into so for 3 months I didn't click off mileage so I have closer to 285k on this car and it is still going. This has been an overall excellent vehicle.
Best body style on the Mustangs until the '05's were released.
No complaints. Not the best riding vehicle out there but she still rolls.
