I had a very positive experience at Doggett Ford in Houston, Texas! The staff was friendly and knowledgeable, and they made my truck buying process smooth and stress-free. My sales rep Chris was helpful and answered all my questions. I felt like they were truly looking out for my best interests, not just trying to make a sale. I highly recommend Doggett Ford to anyone looking for a car or truck! They are top notch.

Kevin has been my service rep since I bought my Jaguar XF
Kevin has been my service rep since I bought my Jaguar XF in 2012. He is a primary reason I love my car as much today as I did when I drove it out thirteen years ago. When I bring my car in for its annual checkup or when there has been an issue with the car, the service has been first rate ? problem solved, quick turnaround, and my car is spotless when I pick it up. I love my Jag and Momentum has been a pleasure to deal with.
