First time car buyers

So the past two weeks it's been crazy. I thought I would have a good relaxing weekend, but with work being so stressful, it was even worse. Two weeks ago, I went to purchase a car with some "new comers." To be honest, it was my first time also. I've always "heard" from my wonderful older siblings on how to negotiate and how buying a car from the dealer has it's pros and cons. Whether you're buying it used from someone or buying it new from the dealer, there's always going to be pros and cons. So anyway...lets give you the short version of the long story.

After testing out the car (not me), they decided to get the car. So we go into the office to negotiate the price. Without question, the Sales Manager punches out some numbers and gives us the cost and the monthly payment. The sales manager gives us the sticker price on the SUV. I started to giggle and said to the guy, "What if I don't want to pay the sticker price? I want to pay the invoice price and we are going to put $10K today what can you do?" What do you know...I guess it's so hard to sell cars now, the guy even took out the invoice for me to look at. Over all, I basically got what I asked for, for the car buyers I was with. I'm kinda proud of myself for the first time doing that. I'm sure I could have done better, but I was punching numbers and trying to calculate everything, and what do you know???? School does help...LOL...my calculations were practically correct, of course, not including the taxes. :) So we took the car home that day after spending about 5 hours at the dealer.

(drama starts.....)

Two days after we took the car home, I hear, "I think the car is too big for me." Oh my gosh, I was really upset. She was the one who choose the color of the car, she was the one who test drove it, and she was the one that said she wanted the car. Anyway...I explained to her, "Once a car is driven off the lot, you lose at lease $5K, AUTOMATICALLY." She said she still wanted to take it back to see what they will say. And what do you know? I was correct, and the worse part, is that you have to pay extra too, because we have to include the tax. So she's losing $7-$8K. That's all of her down payment. So, in the end, she decided to keep the car. Thank goodness. After a few weeks she'll get used to the car. :)
