I purchased a 2014 Corvette here and the process was excellent. My salesperson Eric made sure the car was perfect and that I understood how to use all of the controls. Very plesant and easy to do business with.
Sophisticated Performance Sedan
I purchased the 2021 Audi S6 Prestige after looking at similar vehicles in the class like the BMW M550i and Mercedes Benz AMG E53. My choice came down to performance, reliability, look, and value. I have had the car for 4 weeks and have no regrets. My highway gas mileage has been as high as 31 miles per gallon which is terrific for a car with this type of performance. The controls are easy to learn and the car feels like it is floating when driving it. I like that it is a performance vehicle with an understated look. Some may want a car with a more aggressive look but I like the understated, traditional sedan look. So far I would recommend this car.

Coast to Coast is a very professional dealership. I was treated with respect and professionalism from the time I walked through the door. Dylan and Omar took good care of us from the time we looked at the car to taking a test drive and writing up a sales deal. Coast to Coast carries quality inventory, and back it up. Thank you.

I went in for a test drive.
I went in for a test drive. I’d called ahead and the vehicle (CR-V hybrid) was pulled up front and ready to go. A quick interaction with the manager and the salesman (which may have gone faster because I was already in their system from a prior visit) and we were off on a good test route. The salesman, Sasha, was knowledgeable about his product and easy to converse with, and asked good questions to get a feel for what I was looking for. No hard sell. If all dealership interactions were this efficient, effective and pleasant people would feel more positively toward dealership relationships.

Mirage isn’t a rocket, but as a workhorse outside the city it’s perfect. Bought here two years ago—no warning lights, all service done here. They don’t fake things, just do it right.

Came just to check prices. Asked about leasing, and they literally wrote it out point by point on paper. Even I understood. Still deciding.

Most of my dealings were with Chan.
Most of my dealings were with Chan. He kept me updated throughout the process without putting any pressure on me to buy or not to buy. I finally did purchase a2020 Fiat 124 spider Abarth. The car is everything Chan said it was. Couldn’t be more pleased.
