I had an oil change and a diagnostic for an engine light that wouldn't turn off. They charged $35 for an oil change and $89 to tell me what was wrong with my cylinders causing the engine light. Then they told me over the phone that my car was all done, but when I arrived they hadn't even started the oil change.
I told the owner (Lisle Budden) his prices were high and I told him that even though I knew the mechanic deserved to be paid for his time to diagnose my engine, it was still a bit frustrating to pay $89 and still drive away with a broken car. He then told me that if I found a repair shop that didn't charge a diagnostic fee he would refund my $89 fee.
Well, I took my car to Honcura in Irving and they do not charge a diagnostic fee, even if I decide to get my car repaired elsewhere after the diagnostic was performed. I provided the Preston Kwik Kar owner proof along with the phone number for Honcura and he not only refused to give me my refund per our agreement, but then banned me from his shop for complaining.
Buyer beware. The owner is dishonest and lacks any semblance of customer service skills.
