Well I can assure you my parents were proud of me. Lol. I did all the negotiating, finding financing, and locating a vehicle all by myself. The only thing they did for me was look at it and say they like it.
Since I live in Indiana, we have a Sales Good Act, which I am sure it is nationwide also. But you have the right to come up with a contract between the dealer and consumer. Its something like that. You just have to mention it to them that you want them to fix it before you buy it. If they do and it leads to nothing else then you will buy it type of deal. WIth every contract that you sign you should have a 72 hour window to back out of the deal. That's a law here I believe as well. If something is right or as mentioned in the contract you can so call "re-nig". It has to be in the contract though, anything not on paper is not in the contract, make sure to read all the fine print to. Some contract say you can't re nig something like that.
When they have you sign something they will say "well this is just this and that and all it does is this, just sign here and here".. Still read the print and all they are there to do is sell sell sell. Its something you are trying to buy and you can take as long as time reading it and if you don't understand you can alwasy ask them to clarify. The best way to buy a car is to go with a mind set on what you want and how much you want to pay for it.
Go in one day act like you are gonna sign papers when you finally figure everything out and then if you want, tell them "hmm, well im gonna have to think about it, im not sure if I really want to pay this much, I was thinking more like, $$$$" but always shoot way lower than what you want.
See in my case I wouldn't pay no more than $11k for mine, so I first negotiated waited a week then negotiated some more then messing with number they wanted $500 down this and that and I finally said you know what, how about i bring you a check for $10,000 even out the door. Then the salesman went and talked to the manager. (don't feel threatened by this or worried. Every place does this to pass time so they figure they have you there for awhile you'll make a decision on that because you've already spent soo much time ya know.)
I found out about the power steering problem because it said on the radio. The service light was on and on the radio it said Power Steering. They tried telling me it need power steering fluid. Jacka$$es didn't even look at it because its electric and therefor doesn't need fluid. So there was rst bargianing point.
There are also 4cyl and 6cyl G6's out there so yea 4spd and 5spd this and that. So but I had to drive 45 minutes to get my car one way. so 1.5hr each time i went down there.
So if you have to drive a little ways to find the right one, it sure may be worth it. Call the dealership to see if they have to car number according to there stock number or advertising number, so they don't pull a bait-n-switch on you..
Lemme know if you have any other questions Im still and ammature but can always give good advice.
