I bought a Chevy traverse had a good experience so of course I recommended my dad to purchase a car there I was told due to my referral not being withing the 90 days sorry it took me 2 years but I could of said hey let's go somewhere else anyways it has been 2 months I was promised an incentive of $100.00 yet I have not received anything.
Also my truck had a chip on my windshield when I purchased it no big gyms as the dealership said they would fix it for FREE let me tell u 2 years later and countless promises the windshield was never fixed now my back with Dashiell was broken so of course I call to make a claim as I was told when I purchased the vehicle I would have auto glass insurance I call and I'm told I don't have it??? I look at my contact and no where does it specify what is and is not covered how the he'll do I know they are being honest? I dont!! I would never recommend this place every again to anyone mind u it takes all day to buy a vehicle there and u meet with 8 different ppl
