Car has a 1971 455 Big Block engine that paired with the dual exhaust straight pipe makes the convertible hum. The convertible top is a power top that works great. The body, the engine, the trans all are great. There are no issues with the car. However, with that said this is not a car show queen. It is a car that my family and kids love and have treated well and have used for weekend picnics and trips to get ice cream. The car is owned by a non-smoker. Price is $13,500 Vehicle is sold AS-IS
