Customers always ask us why our cars look so amazing in these photos - That is because all of our cars have been applied with Cilajet ceramic aviation grade paint and surface protection. Cilajet is exterior paint protection that will resist harmful contaminants from adhering to the surface such as: dirt, grease, bird droppings, tree sap, acid rain, raw eggs, salt and mineral deposits. This product has been tested and proven to help save the paint on even commercial aircrafts and the best part is it’s environmentally friendly which reduces water usage, and chemical runoff. The Cilajet application comes with a 1 year warranty from the date of sale. Please add $399.00 to the internet price of the vehicle.

Mike Aziz facilitated the realization of a lifelong dream with patience, kindness and extraordinary professionalism. I bugged him about the car for weeks, even visiting it in person twice before buying it. In every conversation, whether via email, phone, text or in person, he was kind and patient. I was so happy the car remained available when I FINALLY was ready to buy it. Thank you Mike and Phillips Auto! My dream car is now mine after decades of pushing that dream aside.
