  • This was my first visit and I was extremely happy with the service. Even though I dropped my VW GTI off at the last minute with mechanical problems, they were able to fit me it. They kept updated on the progress. My car is now running great! I’ll be back.Toni L.

  • Precise service, responsive, professional, and trust worthy. Do your Porsche a favor and go see Bryan…Thanks for servicing my 07 Boxster!Pinkal P.

  • SST Auto/SpeedSport Tuning is the only place for me! If I had to choose one word: Trustworthy They service my Mini Coopers and my Porsche and the quality of service is beyond compare. I feel like I am entrusting my cars to extended family who not only get the job done right but at a fair price. I had an issue with one of my Minis and SST went so far as to let me know that there was a dealer recall on the topic and that BMW would fix it for free … they saved me hundreds and earned a customer for life. The staff are excellent, the service is superior and I drive with confidence after having work performed. Thank you Speedsport!!David C.

  • Chris did another great job explaining all repairs that were needed on my Mercedes – from the air filter replacement to changing the spark plugs. I never felt pressured. The crew at SST perform repairs right the first time. Without a doubt I would recommend this shop to any one who owns a European car and wants their vehicle running its best. Rachel makes the checkout a pleasant experience – always warm and friendly.Margaret S.

  • Another bang-up job by SST! Bryan was helpful and patient with my questions. Had an MSD 6AL and MSD 8222 coil upgrade installed. My 912 runs much better and would recommend this shop to anyone with a European car, not just a Porsche.R.B.

  • I’ve been going to SST for over 3 years now. I wouldn’t trust my A4 to any other auto service shop. They are extremely knowledgeable about the cars that they service (especially Chris, who knows Audis inside and out). There is no reason to go anywhere else.Barry S.

  • SST is the best! I have 2 Porsches that they maintain and they do an unbelievable job. Their customer service is by far the best of any service center or dealership I’ve ever dealt with. The work they do is top notch and the entire staff is extremely knowledgeable and personable. And they charge a very fair rate for what they do. You will not overpay for anything…ever! Just a very classy operation!Joseph R.

  • I took my 2006 BMW 750li to get my transmission service done, its a big job and a few people are able to do it, had it done in time, works great, washed my car. I like the place, good job. I took my 04 Audi A8L for diagnostics…honest people, great advise, thanks!Alfredo G.
