Glendenning Motor Company review
I really appreciate the way the staff at Glendenning
I really appreciate the way the staff at Glendenning Motor Company take care of business. They aren’t pushy & have no doc fees or added charges. It’s a pleasure to do business with them.

Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Freeway Toyota of Gilroy review
After my experience with my sales team Camary and
After my experience with my sales team Camary and Giselle, as well as the whole dealership I had to come online and share. I’d just like to big the biggest thank and shout out to Camary and Giselle plus the whole Toyota dealership at this location !!! (: From the moment I arrived to the very moment I left I was treated with the most respect, kindness and supportive spirit ever from everyone at the dealership! They were beyond informative about everything I was getting into, they broke everything down from the start to finish. They helped understand things that we didn’t know about as well as get set up with the best perks and benefits ! I would just really like to thank the sales representatives Giselle and Camary again!!! They both went above and beyond to be able to get me an amazing brand new 2025 truck out the lot at such an amazing absolute reasonable price !!!! Everybody was so transparent about the process and the information and what to do moving forward. They even provided Additional important information about the car that I traded in that I did not even know about. This is an amazing team and dealership. I truly thank everybody involved in the process. I definitely will be back for my fiancé in a few months and hopefully as well as my grandma.

Great luxury ride with great pulling capabilities.
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.
