i took my 1986 bmw 528i to these guys because it wouldn't pass smog. numerous other shops told me it would be over $3,000 to fix all the problems. i took my car here and they hooked me up. they replaced the bad sensors with used ones they had laying around so they only ended up charging me for labor. they even hooked me up with a couple used tired for only $20.00 a piece. the manager Corey was super cool and he even changes the tires for me personally because my old ones were wearing through and you could see the metal belts.
