Always a pleasure going there for oil changes, Dave and the staff are always pleasant, I used to go to Jiffy Lube until they screwed up my car, found Diamond Automotive and have been going there ever since. They take the time to check your car, rather than Jiffy Lube who always wants to “check your cabin filter” etc….. And then tell you that you need brakes, rotors, and give you a printed estimate…. Dave checked my brakes, and rotors, they were completely fine!
