    They got my smog test done in less than 10 minutes! I went around 3PM. Don't forget to check in on yelp! They are professional and very fast.

    Pulled right up, welcoming staff and got to work quickly.

    3 years later... I've taken my mother's, my brother's and my own car here several times and they have always welcomed me right in. One of my cars failed smog and the worker advised me on how to clear the errors and to return back the same day or next to pass the smog without being charged for the full service again. Currently here again with my mother's car and once again they welcomed us right in and the worker began work immediately. I can see he's wrapping up which means we were in and out of here in about 20 minutes total. I still highly recommend this place for the service, the speed, and the value!

    Front of business. Turn into driveway going to California Reflection and make a right.

Sunny and Omar were great. They greeted and opened the door for us as we approached the front entrance. It was very warm and welcoming. Everyone should buy their Porsche from this dealership. Tons of parking and great inventory. Thank you for making it a memorable experience for my wife. She got her dream car! Special thanks to Sunny for taking his time and explaining everything and making sure we understand everything in his office, very patient.

    I used to love this dealership, and my previous reviews below show it. I don't like writing…read moreone-star reviews, and I spent enough time explaining to them how important it is to be fair and not forget the dealership's longtime clients. I was recently offered a 2026 GT3 Touring. They asked me $50K over MSRP to "start building a business relationship." I heard those familiar, luring words all over again. They apparently forgot that I've bought multiple GT cars from them, paying more than $50K in markups on each one. I made it clear that I was uncomfortable with the markup, but they still asked me to come in, so I agreed to have a dialogue. During the negotiations, I reminded them of my history with the dealership, including how many cars I've already bought and the nearly $200K I've paid in ADMs over the years. Their response was, "Its new ownership, and you need to give us something." Apparently, my entire purchase history was wiped out the moment new ownership took over. They obviously want my business, but only under their terms--and, in my opinion, those terms are sketchy. I'm actually glad they approached me at a time when I don't need to buy from them. Nevertheless, I would always consider buying a cool car. I hope this review helps some Porsche enthusiasts who are excited about building a relationship with this dealership, as well as people like me who may be seriously considering coming back.
