My car (91,000 miles) had been leaking coolant from the cylinder head gaskets for months, and I received quotes for the work from the nearby dealership and three private repair shops. Diablo Auto Specialists' pricing was not the lowest of the group (although all four quotes were in the same range), but Tim offered me a 3 day paid-for car rental--which the dealer also offered, but the other two private shops did not--as this was a 3 day job. Tim also included several extras in his quote to me, such as new spark plugs, air and fuel filters, and radiator hoses. During the inspection, Tim's mechanic found 3 other issues with my car, one of which (torn axle boot) I was aware of, one (rear brakes down to 3mm) that I was not surprised about, and the last (broken rear windshield washer pump) I was unaware of. He didn't push me on these findings, but I chose to have him replace the axle assembly, and hold off on the others. During the 3 days he had my car, Tim kept in contact with me, and, although it's only been a few days, my car has been running great since I picked it up. Diablo Auto Specialists has a nice, convenient location, and I find Tim/his shop to be honest and very likeable. I shall look to them for my next service or repair.
