We Only Sell the Good Stuff

At PDP we only stock the highest quality parts & accessories. Honestly, if we wouldn't put a part in one of our own cars, neither should you. We won't recommend a product to you that we haven't worked with ourselves. We stand behind everything we choose to stock in our store.

We're Here to Give You a Hand

Just like our cars, we like to make sure we go the extra mile. We still like to think of ourselves as the small business we started out as, which means reputation means a lot to us. Whether you just need some advice, or your stuck mid-installation, give us a call and we'll give you a hand.
