The 1991 Prelude was a great car. If it was maintained properly, it will continue to run for many more miles. Some things to double check is the when the timing belt was last changed and the CV axles. If the car has 4WS (4-wheel steering) check both the front and rear tie-rod ends.Since you are in the market for a Prelude, I would recommend looking for a 1992 - 1996 model. The Prelude had a major update in 1992 that gave it much more power and refinement.
