Great service and the service was done Quick on time?
Great service and the service was done Quick on time? we moved south to Rosenberg but I don?t bother drive up to the sale dealership for my service?
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

The best Houston has to offer in RV repair work.
Our Mercedes Era motorhome sustained serious damage while passing through Houston on I -10. It was no longer driveable and we were still 4 hours away from our home in San Antonio. Having spent 35 years investigating and resolving claims for a large insurance company, I was versed in physical damage restoration. Unfamiliar with Houston body shops, I relied upon the advise of a Foremost Insuance claims manager and he said, “DeMontrond RV Collision service is the only shop we could recommend.” On their advice, I contacted Jeff Sayers and I’m so pleased with their thorough evaluation and outstanding repair work. They located all damaged parts and relied upon Mercedes for any mechanical needed on the MB diesel engine. They finished repairs on the date promised and did professional work on body restoration. They communicated with me on a regular basis. Their friendly and knowledgeable staff documented all damage with photos and detailed explanations. This “0ld Claimsman” was impressed.

We recently bought a car from Javonte at Becken Masten North and his service couldn?t have been better. Will continue to go back to him on the future. He did not push and ensure we got exactly what we wanted within our budget. Very patient and attentive.

Great customer service!
Shopping for a car for my granddaughter we visited Demontrond Volkswagen in Spring one afternoon. Steave Castillo(Cajina) ,sales consultant, met us outside and proceeded to show us the cars and answer all our questions. Great salesman, no high pressure. After checking other dealerships we returned to Demontrond and completed our purchase.
