mia was great to work with and I'll recommend all my friends and family to her.
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Although I didn't walk off the lot with a car, I will say
Although I didn't walk off the lot with a car, I will say I very much enjoyed my experience here. The gentleman I dealt with was very nice and courteous. Wasn't at all pushy and tried to work with me the best he could. They even had someone drive the car 20 minutes out to see my technician. They really went out of there way to make things work. Unfortunately, we were not able to work things out, but If ever need to shop for a car again, they will be on the top of my list to check out there inventory.

Great RAV4 buying experience from Westboro Toyota
My wife and I have had wonderful experience buying the new RAV4 XLE 2022 from Westboro Toyota. Ricky was the first salesperson with whom we discussed the need for a new car. He is very professional, knowledgeable, and respectful and explained everything that we need to know about the new car buying process very patiently. We had to wait for more than 2 months to get the car with the color of our choice. Whenever I called him or texted him, we have received responses which encouraged us to wait patiently. 3 days ago, we have received a call from BB, a genuinely nice, knowledgeable, and respectful salesperson or manager who explained to us the availability of the Car with the color of our choice. We have had friendly conversation with BB and the Finance Manager, and we got the car in 2 days after completing all works related to Car buying. It has been a wonderful experience. Also, we would like to let you know that we have been getting excellent service from the Service team for other Toyota vehicles for 11 years. We would highly recommend Westboro Toyota for great buying and service experience.
