Diagnostic services service near Bensalem, PA

Been taking my imported car problems to Fred Sonsini off and on since the 1990s. Terrific service, high integrity, fair prices, extensive knowledge and experience. "Old school" in the best sense of the term. Highly recommend.

Too bad I cannot rate them with 0 stars as 1 is way too much. took my car for an oil change and found an oil piddle under my car the next day. the car is 3 years old and never leaked. took the car to the authorized dealer and they told me that "who ever performed my previous oil change did not do it right". in addition, it did not feel good when they tried to sell me all these unnecessary things including the break system flush after it was done 6 months ago. don't take your car there. they cannot do a simple job as an oil change right, but they will try to sell you everything you don't need.

The work was performed as described and the job was on time and under quotation price. The parts needed were quoted as OEM price or aftermarket price for my selection. Good workmanship and towing service provided.

This place is reliable, honest, neither slow nor fast, and is economical. It is best to call them during working hours, describe the issue(s), and set an appointment for drop off. They allow you to drop the keys through a mail slot and leave your car if dropping off before they open. They call you if there are issues and when the auto is ready for pick up. They offer great services, at good prices, give decent estimates, and communicate any issues during the process. The only drawback is that Tom is kind of a curmudgeon. He is a very honest and trustworthy person, but is grumpy nine times out of ten. My wife and I have been going to Stephanou's for about seven years or so. They are awesome.
