Covert Buick GMC in Austin, Texas

I am very disappointed with Covert. While in the process of purchasing my 2017 Terrain an accessories sales person talked us into buying a full liner for the cargo and back part of the seats. I was charged $250 for this. They told me it took about 1-2 days to install it and it ended up taking them about 5 days. I get my vehicle and all I see is a plastic mat for the cargo area nothing like what the sales person had showed us. It turns out that the accessories sales person showed us accessories for the 2018 Terrain. Had we not said anything I would have kept a $50 mat and paid $250 for it. When it came to signing paperwork, the finance person had my husband sign as the applicant and me as the co-applicant even though we had told him the vehicle was for me and I'd be paying it. I know this is not a big deal, but I did not like it. The only reason I put my husband on the application was because I like to have him as the co-owner of whatever I get. I have good credit and good income to get a vehicle on my own. When I actually got my vehicle it seemed like they had not cleaned it. I just shrugged it off because it wasn't a big deal, but then I saw that one of the tires had low pressure and that the oil life was at 24%. I thought they cleaned and checked all these things before giving it to the owner. All I know is I am not going back and buying a vehicle there again.
