This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

This Place Will Save You Time!!!!!!!!
THIS PLACE WILL ABSOLUTELY SAVE YOU A WHOLE LOT OF TIME!!!!!! I began my search in January of 2017 and after 5 weeks only found myself exhausted, frustrated, and still without a vehicle. I searched in Hollywood and Los Angeles and all I found were run-down dealerships and some well-kept but full of snakes. Most wanted down payments that will far too much. The mileage on the average vehicle in those areas was absurdly high for the prices and terms they were asking for. The cars were also lackluster for the prices being asked. I thought this was the common trait and steadied myself to make a decision with a sheisty company. They actually showed me a vehicle (and assured me they could hold it for 24hrs) and within an hour of me calling them back to begin the process of purchase, I was told that it had been sold but that another vehicle was available. Such a negative experience. TM MOTORS WILL PROVIDE A POSITIVE EXPERIENCE which may a world of difference to a person stressed out from my search to purchase a worthwhile vehicle. I bought my vehicle from them in February and have had absolutely no problems with it. In fact I'm in the process of purchasing a new vehicle from them before October is up. No gimmicks, just great cars, and I dealership that helps for repeat business so they treat everyone fairly. Before purchasing from them I tried one other company in Anaheim and found them to be completely Shady. They attempted to sell me a 2001 hybrid at a super high price (6000) because of his low mileage (30,000). When I took it to my mechanic it was easy for him to tell that the cells were about to give and that replacing it will cost me another $2,500. That kind of trickery will not occur with TM Motors. I'll check back in 6 months from now with an update, but I'm honestly telling you these guys provide a great experience and can work with most anyone's credit to get them in a great car Within 2 hours of walking in or less ?

Our family has been taking our older Highlander to Toyota
Our family has been taking our older Highlander to Toyota of North Hollywood for 15 years now and are grateful for the wonderful service we receive. Paul Carrasco is one of the kindest and most communicative service advisors I've ever had the pleasure of working with. He truly listens to his customers, wants to serve them well, and has a caring heart. Before working with Paul, we appreciated the help of other service advisors who were also professional and considerate. Toyota of North Hollywood has one of the best automotive service departments I've encountered and I recommend them wholeheartedly!
There are 20 matching cars close to your year range.
