Welcome -- At Performance Prep we believe that the automotive industry has been and is still evolving into a very hi-tech industry. Along with the evolution into safer, cleaner more fuel efficient vehicles some things have changed. Regular care and maintenance has become more important and today's vehicles are less forgiving for missing the scheduled maintenance. In most cases the fast food approach to automotive care may appear less expensive and convenient in the short run. It has become more important to build a relationship with your auto care provider that takes your needs and your vehicle's needs seriously. At Performance Prep we have been establishing these kinds of relationships since 1981.

We have invested time and money to make sure we have the latest equipment and training to service today's vehicles. We appreciate your time in reading this and if you give us a try we won't waste your time or hard earned money.
