Had service on my wife’s RX 350 at Bell Rd Lexus
Had service on my wife’s RX 350 at Bell Rd Lexus yesterday 12/3/25. The service consultant, MATT COLTON was the best advisor that we ever had, anywhere! He was patient, respectful, professional and genuinely interested in our needs. Being received with a smile and a hand shake was refreshing! THANK YOU Bell Lexus for having a great man help us!

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Great Reliability
Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

Steve Souther is the guy!
Steve Souther is the guy! I called from San Diego and he helped me from beginning to end and always responsive and even answered me while he was doing a charity fundraiser! I strongly recommend them.....
I LOVE the power
I really enjoy the Terrain. Traded in our beloved Mercedes R350. It was dream to driving on the highway. Our list for new vehicle was easy to get in and out without climbing up or down. No leather seats, hate leather seats, panoramic roof, engine power, get up and go, some luxurious in the vehicle, an easy info console. Before we took a test drive, we did our following tests. How easy to get in and out of the vehicles, leg space (our son is 6'4"). Only wanted two row seating, comfort seating. We checked all other makes. Spend awhile day going from different Dealerships of different makes and models. Didn't want to speak to car salesman, just let us do our preliminary test, on different makes and models. Then we look at the warranties. Finally took take a test drive. Was blown away at the get up and go of the Terrain, pleasantly surprised at the safety features and options it comes with. After almost a month, trips outside the city to the mountains and back. We are really happy with the purchase of the Terrain. Seven years warranty bumper to bumper, ten years on the powertrain. The true fuel economy really surprised me, it doesn't bother me that I have use 91 fuel because of the 2 liter engine. Had to use it on the Mercedes so no change there.

I’m not one to praise car dealerships but my experience
I’m not one to praise car dealerships but my experience with Carizona has earned it. Sales guy AJ was great. No xx, no pressure, all good vibes. Same with the manager and the finance team.

GARRETT IS THE BEST SALESMAN !
GARRETT IS THE BEST SALESMAN ! He was spectacular in every way. Even though he's young, this old chick can see he's going far ! Very personable, already so knowledgeable, friendly , happy to help. I told him I wanted to get in, buy the car and get out, no time to waste. He had the car sitting in the front and ready for a test drive. It was already clean, but he offered detailing if we wanted to wait for it, we had to decline, but honestly it didn't need anything more. He had the carfax ready and already gave the finance dept the info of the place we were working with on the loan. THANK YOU GARRETT for making this a happy experience. TEN STARS !!! Mary & Eric
