They guy Joel does a great job and great person love his customer service i will be back again for another oil change because of him
A little expensive, but comfortable, quiet, smooth ride.
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

My scheduled service to replace tire and 5,000 mile service was in and out in great time for what had to be done.

Once again, Vikki did a fantastic job of taking care of
Once again, Vikki did a fantastic job of taking care of me and my truck. I scheduled the 100K service for my truck, and then got a curveball that made keeping the appointment more of a challenge. Vikki was able to help me reschedule my appointment in a way that still aligned with my schedule. Vikki?s attention to detail, knowledge, and responsiveness give me confidence in services/repairs being done right the first time. Her care and understanding of how to take care of her customers makes DeMontrond the only place where my truck will be serviced.
