Amazing experience
I was in the market for the new Sienna XSE with some upgrades and couldn't find what I was looking for. I was in contact with A LOT of dealerships and they were just awful. I finally called Longo and was able to reserve a Sienna XSE that was coming from the factory, with the package that we wanted. David Fearn was awesome, he was understanding and helpful. We had a lot of question due to our previous experience and he was more than happy to help us. When the vehicle arrived we were a little afraid it would be sold from under us but again David was understanding and reassured me it would not. So we were able to relax and come in on our day off. I believe we spent about an hour finalizing everything and then drove home in our new Sienna. Its was such a quick and amazing experience, I definitely recommend Longo to anyone looking for a new Toyota.
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!

Thank you to your dealer and your staff for helping us
Thank you to your dealer and your staff for helping us choose the best car for us, special thanks to Yura for giving us good service.
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.

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.

AMAZING!!!
I want to start off with the compassion this place has for the customers. I never once felt pressured for anything when being here and talking with the sales reps. I had the pleasure of doing business with Rami. He took things at my pace, was very understanding and I felt tried his hardest to get me into the car I so desperately wanted. He kept me updated on the car and walked me through each step making sure I was comfortable and answering my questions to reassure me of what was going on. Then came the gorgeous Vanessa who emailed me during the week to make sure my dream car was still available. When I went into the dealership she introduced herself and sat to talk to me even though I was working with Rami. She was very nice and also made my experience that much better. She honestly cared and I could tell by how passionately she spoke to me and could see it in her eyes. Last came Argenis who tried his hardest to get me the best deal I could handle. He was very professional and walked me through everything. He made the experience very comfortable and I am very pleased with my whole experience here. I would recommend 10/10. My best experience by far with any auto group.

I had a smooth and excellent experience purchasing my new Mercedes. My sales agent was wonderful?never pushy, truly listened to what I wanted, and made the process stress-free from start to finish. Everything was transparent with no hidden agendas, and I felt completely comfortable and confident in my decision. I highly recommend working with her if you?re looking for a professional and enjoyable car-buying experience.

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.

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.
