I was referred to Allen's by a friend who is an ex body man and mechanic a couple years ago when I had problems with my a/c on my commuter Civic. Eric charged a minimal amount for a dye test and found the problem and took the time to show and explain to me exactly what it was and I was able to fix it myself.
Last week my van was having a cooling issue that Eric scanned the code and told me exactly what the problem was again, which was the cheapo thermostat I had installed a few weeks prior.
5 days later my Civic's timing belt snapped on the 101 and Allen's towed me in, diagnosed it quickly, advised me on everything needed and charged a very fair and reasonable amount for the repair. Repairs were done quickly and the car drives perfect.
What else can you ask for than an honest business that charges a fair amount for quality work?
