My family have been loyal customers for well over 20 years, bringing our cars to Central Import the moment they're out of warranty, and also bringing potential purchases to be checked out for an opinion.
We've had Hondas, Mazdas, Volvos, VWs and BMWs (oh yeah, and an Oldsmobile, if anyone knows what that is ;)) serviced, virtually always perfectly. The one or two rare times things weren't fixed right they were rectified immediately to our satisfaction. We've never felt anything but well advised and fairly treated; I don't think we've ever paid for unnecessary work.
Why 4 stars and not 5? Despite the trust and loyalty, despite the fact that I know you get what you pay for, my limited budget may be forcing me to explore cheaper alternatives as Central's hourly labour rate is cca $100. So no complaints, great service, but I'm not sure I can always afford to fly business class, sometimes I have to fly coach :). But if this price works for you, don't hesitate.
