Reviews
I was very satisfied with Zaid and the rest of the staff
I was very satisfied with Zaid and the rest of the staff at Twins Auto of Dublin. They have a great selection of used cars that tend be "higher end". Zaid was extremely knowledgeable about every brand and model. He wasn't overly pushy, which I appreciate. They were quick, painless, and fair when it came to negotiation and the financials.
Great Vehicle
I absolutely love the feel and performance of this suv. The electronics are state of the art. Excellent road performance in rain, snow or wind. My only complaint is the running board- it needs to be at least 1 inch wider. Actually dangerous in snow and ice.
There are 5 matching cars close to your year range.
