I purchased a 2024 Honda Civic Sport on saturday and I had a very pleasant experience with the sales rep, Michael Comley. He was extremely helpful throughout the entire process and gave me a very fair deal that stayed within my budget. . He took his time to explain and answer all my questions.I highly recommend Mike.

2018 GMC Yukon SLT review
Safe Vehicle for traveling
This car is a fabulous car for family and traveling. It is roomy, has capacity for kids and sports gear, and is safe. I have been rear ended twice in a Yukon and there was minimal damage to the Yukon and extensive damage to the other vehicles.
There are 10 matching cars close to your year range.
