Love them.
Love them....always fix my Jeep with utmost care and expertise. Always follow through and check that all was done well.
Most incredible car I’ve ever owned.
This is my second Mercedes-Benz. It’s absolutely the most incredible car I’ve ever owned. I was blessed to be able to custom order this car to have everything I wanted and more inside and out! It literally came straight from Germany to the dealership for me. It drives like a dream. It’s absolutely gorgeous. The technology inside is so amazing! It can drive economically. It can drive more sporty if you want it to. It has so many options and settings for drivers of all kinds. Needless to say, it’s pure luxury inside. You’ll feel incredibly spoiled!

Found the exact Civic we wanted and worked with our Budget! Thank you Armando and the Honda World team!
Haven't put many miles on due to snow and ice.
Not enough miles driven to fairly evaluate but look forward to driving when weather is better. I have high expectations! I'll need time to get used to the console controls.

Private Collection is the place to go for exotica
We were extremely impressed with their showroom, delivery, no haggle pricing so we did not end up spending a day waiting for the sale manager to work you into all the stuff you do not need. I came to pick up the car next Monday they have the car all detailed up for us. I will return for my next purchase.

I traded in my car for a better one at lower payments.
I traded in my car for a better one at lower payments. I'm very happy with how they treated me, didn’t push me, didn’t try to fool me. I looked at 4 different vehicles and ended up with a Toyota Tacoma, car’s history was very transparent and the price for its condition was superb. Overall - very positive experience.

The service by Bruce was top notch and the car is high impressive for its design and functionality. I didn't expect this level of quality! The buying experience and how I still enjoy the car itself increased my value and interest in this brand and this dealership in particular.

Great Service
We had a great experience with Pacific BMW. The car we purchased was beautiful and we got a great deal for it. The only negative part of the purchase was the actual buying process. It took a little longer than we expected and maybe it could have been a bit more streamlined. But in the end, the car was worth the wait.

My first interaction with a representative from STG via
My first interaction with a representative from STG via cel phone did not result in a transaction that met my satisfaction. Some days later I was contacted by a different representative and things went very smoothly. Caesar Q and I reached an agreement that he confirmed by email. I drove down from San Jose with my trade in vehicle and a cashiers check and arrived well after dark. The truck was prepared and ready for me to perform a thorough inspection and test drive. I was inside, outside and under the truck and it was very clean and looked as good as it did in the photos. Caesar was a pleasure to meet and work with. Very friendly and easy to communicate with, he and I shared some similar interests. The paperwork went smoothly and Caesar explained everything about the process as we went along. I would not hesitate to shop at STG in the future even though it is a 7-1/2 hour drive for me. Thank you to Caesar Q and STG for making my truck buying experience a pleasurable one. Respectfully Thomas O.

EASY Carbuying experience, great service dept!
I bought a 2004 Pilot a month ago here. My salesman, Tim, knew exactly which loan to submit me for because I had no job and bad credit but a big down payment. He had me financed with no problem in minutes. A few days before I went to Carmax Burbank for a different car but with the same down payment and the saleswoman there did not do the same thing. The car was purchased in 2 hours and I was driving home. I bought the warranty tey offer which is a great bumper to bumper extended through their company. They have a 5 day return policy. I opted to return my car on day 4 to pay for the warranty in cash so as not to finance it at the very high interest rate I bought the car at. The return was also easy and everything was done in less than an hour. A month later now, I have found a few things wrong with this 2004 that seemed to have slipped past their extensive reconditioning program. I took it in with odd complaints a dealer would normally say they couldn't duplicate. They addressed them all and even gave me a loaner SUV for my babies to fit in while I waited the few days for the parts to arrive. GREAT STORE! Great customer service! And there's a play room for the kids! *Avoid the coffee!! It is terrible!!!

This is my first experience with Fletcher Jones and it
This is my first experience with Fletcher Jones and it has been a good one so far. Buying a car long distance, sight unseen is always a bit of a challenge and potentially a risk. I feel very good about the responsiveness and customer care provided by Fletcher Jones staff. As car delivery is still in front of us, the jury is out on this experience, but I anticipate a very positive outcome. Fletcher Jones reputation provided a lot of confidence.

Purchased a Mercedes-Benz E55 AMG
I purchased a used Mercedes-Benz E55 AMG from the Carmax in Costa Mesa, CA about a month ago. I started out by calling the Carmax and reaching a sales agent. She worked with me by setting aside the car so that I could fly down to pick it up. She picked me up from the airport about 15 miles away from their dealership. When I saw the car, I found some minor cosmetic issues with the car and Carmax assured me that they would repair them at my local Carmax in Roseville, CA. I will be writing a review about that Carmax as well. They issued me a form stating repairs to be done at my local dealership. I informed the salesperson that I would be pushing the car a bit and she was fine with it. After the test drive, the car seemed to be in great condition, so we headed in for the paperwork. The appearance inside of the dealership building did not convey a welcoming feeling though. It felt like a warehouse with desks in it. The people within the building were nice and friendly though. The paperwork was pretty quick as I already had a loan check from the credit union. It took about 30 minutes and then I was on my way. Overall, I would say the experience was positive.
