About Us

Proper Performance Motors Inc is a family owned business with more than 40 years combined experience in the automotive industry. We are your source for providing the rarest and most desirable cars from the 90’s to the present. We call these Future Collectibles. These are cars that are just beginning to rise in value and will continue on an uptrend.

I remember as a young boy reading through Dupont registry and dreaming of my future garage. Over the years, I have become a true enthusiast of all things European, especially BMW M's, Mercedes Benz AMG's, and Porsches. Although, we do love our Ferraris, Lamborghinis and McLarens!

If we don’t have what you are looking for, trust us, we will find it. We believe in long term relationships and look forward to becoming your dealer of choice.
