I'd much rather buy a house over a car anyday.
I'm with you. At least a house appreciates in value.
In 2001, we decided that it was time to buy a new van for me. We checked out several dealerships looking for the best deal. We went to a Dodge dealership in a neighboring town. As soon as walked on the lot, a salesman was assigned to us (I hate that). We knew what we wanted, so it was really a matter of test driving it and choosing the color. I chose the one that I liked and then went inside to get an idea on price. There were some incentives going on at the time, cash back and low interest financing.
The salesman asked to look at our car (trade-in) to give us a value figure. After a few minutes, he came back into the cubicle with all these outrageous figures. One of which was $300 (I laughed) for the trade-in and another figure for more than $1K (double laugh) for the monthly payment (I think it was a 24 or 36 months deal) and also included $3K from us for down payment. There is no van or car on this planet that I would pay $1K a month for. When my husband saw those numbers, he asked for clarification. When the salesman was done explaining, my husband told him to give us our keys. Well, it went downhill from there...
The salesman wouldn't give us our keys and kept asking my DH why he was so upset. DUH!!! He told the salesman that his figures were a total insult and didn't want to do business with them. My DH kept asking for the keys and when the salesman refused to do so, he stepped into the lobby and said very loudly, "Will someone get me my keys?" Every person that was in there began staring, I just walked out and waited outside for DH. DH says that immediately another salesman came to him and asked what the problem was. DH explained that the salesman wouldn't give us our keys, the manager came out and we finally got our keys. Then, of course, we couldn't find our car where we had left it, so DH had to go back in to ask where it was.
As we were finally walking toward our car, the salesman was chasing us. He kept apologizing and saying that we should go back because they had really good food on the second floor.

Maybe we looked hungry?

The guy was a complete jerk.
Needless to say, we will never go there again and have told anyone that asks for info about car dealerships about the incident. About an hour after this happened, the manager called our house wanting to make a deal for us. He continued to call for several days trying to sell us the van.
In my experience with buying new cars, you have to be willing to walk away, to have a good credit rating/history and have money in your hand for at least a decent down payment. When the salesmen know that you aren't desperate, they work harder to earn your business.
