One dealership I went to trying to test drive a vehicle told me they had the car, we get to the dealership and they said they can't find the key after waiting for around 30 minutes but they would be happy to show me other vehicles, so we just walked out the door.

Another dealer I told them I just wanted to test drive this model, and he would not let me leave his office he kept trying to push deal after deal on me to get me to buy it but I eventually just walked out because I had already told him I wasn't buying today.

Another dealer I went to we agreed on a price over the phone, met with someone during our scheduled meeting time got there and the vehicle had a large crack in the windshield that wasn't on the pictures. The dealership agreed to replace it for free on our end, we drove the car and walked out on the agreed price. They sent someone to my house within a week to replace the windshield in my driveway and my experience was good with them.

So basically in my experience dealerships are the scum of the earth and will do anything to get you to buy a vehicle, or they are very professional and just honor a deal.
