My transmission went out on my suv.
My transmission went out on my suv. I was in middle of commuting from Texas to Arkansas for work. I called the dealership and was guided to a towing service that was highly recommended by them and once my vehicle was brought to their shop. The receptionist took care of scheduling the services I would need. The problem was identified and repairs were done promptly.
COMFY CADILLAC
My car is 15 years old. I've had it for ten. I got 29.5 mpg on my trip to Santa Barbara over Easter. Problem is is that is doesn't always start the first time. Supposedly has 'extended crank' which could mean the check valve in the fuel tank. The local dealer never could figure it out. To repair it will be cost prohibitive, so my search for the XT5 continues.

Above and beyond service
I have never bought a car online before let alone bought a car without even seeing it or driving it. I saw a Bentley Flying Spur for sale at Chicago Auto Gallery. I called and spoke to a salesperson named Steve. From the first hello on the phone until we closed the deal and the car was shipped to me Steve was fantastic. He did everything possible to ensure that I was satisfied with the car and the deal. Now here's the extra part that I was even shocked at myself. Once I got the car, I drove it and after 5 miles some of the lights came on such as check engine, ride height, traction control and ABS. I was initially immensely pissed. I called Steve and said you might want to get ahold of that driver who delivered this car and tell him to take it back. Steve suggested I take it to a certified mechanic near me and have it looked at to see what was the problem. Apparently when one light goes off, it triggers more lights to activate. I had it looked at and to fix the car right it was going to be over $3000. Steve took care of it and the dealership paid the whole bill. In my mind that was the most solid thing to do and he did it. He could have argued and tried to avoid it or said no, you bought it, you fix it. They did not do that to me. I'm in Pittsburgh and they are in Chicago. I know I had rights and could have just sent it back but I wanted that car and they fixed it for me. I appreciate everything they (Steve) did for me and I would definitely purchase another vehicle from them. Thank you again Steve and Chicago Auto Gallery.

Solid Cadillac xxx
Honestly solid built car by GM, unfortunately cheap interior, my car has 105k dash has a crack on it seriously for a 54k new car it has cheap gm plastic lol but other then that I only had to replace a oil pressure switch and the ride hight sensor its been a fabulous car better then the predecessor bar none! If you keep up with the oil changes you won’t have to worry about the cam phasers going bad on you basically keep up with basic maintenance and this car (like any car) will last a long time, despite its weight and size it’s very agile because GM tuned it’s chassis at the Nurburgring hence the sigma platform overall I believe this car will be a future classic GM did the Northstar LH2 right compared to the previous Northstar generation don’t be intimidated by the Northstar name because any aluminum block design engine has its flaws, if taken care of properly this car is honestly as good as a Lexus, like I said very solid built Cadillac compared to its predecessor, I would buy another one with out a hint of regret, test drive one with a Northstar I promise you won’t regret it! Definitely lives up to the Cadillac standards other then the cheap GM plastic including the fake wood by the HVAC and radio(real wood on the door handles and steering wheel) but if you over look that then you have a definite under rated car.

I recently called Monaco Motor Group about a Porsche they had, and I'm really kicking myself for not acting faster. By the time I decided to go ahead with the purchase, it was already sold. They were uber professional and helpful throughout the process. The gentleman I spoke with, Aamir, was very well-spoken and articulate. Even though I didn't end up buying the car, I was very impressed with their service. Would definitely consider buying from them again.
Best car I ever owned!
Awesome car. Hate to see it go. Been in the family for 10 years. Very fast and comfortable car. When I first saw it, I fell in love.

I am writing ANOTHER review for Trend Auto since I
I am writing ANOTHER review for Trend Auto since I continue to use them for maintenance issues regarding my used Toyota Sienna that I purchased from them years ago. I have had several issues pop up through the years regarding my van and not only have they resolved each and every problem, they did so in a very reasonably priced and expedient manner. I cannot say enough good things about Trend Auto. I would not even consider going elsewhere. I trust these guys 100% and KEVIN IS FABULOUS! He is honest, fair and trust worthy. They all are an absolute pleasure to work with as I have never had one negative interaction with anyone there. In the past, I have bought many vehicles from various dealerships and I can tell you that Trend Auto is the best!!! I cannot recommend their top notch service highly enough. They are excellent!! ⭐️⭐️⭐️⭐️⭐️

Great dealership!
Bought a 2005 Lincoln Navigator, 145k miles. It's in excellent shape, no issues since I've purchased it. I think they're an honest dealership. I would use them again if I needed another used vehicle.

We went by to look at one car but it was out for repairs. Our second choice was available so we took it for a test drive. We were so pleased with the salesman, Amir, who was so calm, helpful, and honest with us about our car options. We thanked him for facilitating such a chill car buying experience.
There are 19 matching cars close to your year range.
