    My husband has been a long-time customer of TEM - he had several of his racecar engines…read morebuilt/rebuilt by TEM over the years, and a glance at his trophy case tells me TEM did a spectacular job! After all these years, I finally visited the machine shop myself at their newer location in Cotati. Rich and his crew were so friendly and knowledgeable. The shop is amazing - clean, organized and huge. Admittedly, engine building is not in my skill set, but I know my very particular, racing-obsessed husband would not trust his cars to anyone but an absolute expert! So I trust that Rich and his crew at TEM must be the best. I also walked through the adorable bookstore, Books and Blocks. It's such a cute and friendly space to find great priced new and gently used books!

    I have a 2009 Maserati Quattroporte Executive GT 4.7 since new. I love that car WAY TOO MUCH, so…read moremuch so that i changed out the entire cooling system, 3 engine mounts, front upper-lower control arms, 4 suspension w/ bushings, 3 front speakers w/ amp (Bovee bluetooth converter)...all done by Ferrari Maserati dealer; not the stereo. Then came the real test...variator. TEM Machine Shop was the recommendation n it was a major surgery. But full credit to TEM and dealer Ferrari tech bcoz after TEM variator installation, my Maserati now runs so beautiful that my son, after 1 ride, who cud not care less about cars (ancient Volvo driver) asked, "Can i buy this off you when you'r done with it?" But why wud you want the Maserati? "The way it runs is smooth as butter. I can tell the engine is operating in complete mechanical Zen." Yes, TEM parts works amazingly well and now i am so VERY tempted to buy a Maserati Gran Turismo just so i can replicate the same mechanical Zen in a 2-door GT.
