I clicked on a link Verslagen put on here about buying used bikes. Reminded me of buying a 92 Olds with my wife along. Long story,short--we loved it during the test drive. Came back and I told the salesman we couldn't pay a dime over $250 a month. My wife spoke up, eager to help, and said, "I'm getting my raise next month because of a good evaluation by my consultant! That'll make up the difference." The salesman gave me a sad look and I think he almost felt sorry for me. Almost. And it was a good car.  

Here is my advice for buying big ticket items---PATIENCE!  

The only new vehicle we purchased was an '89 Forrunner. My wife and I test drove all the new 4WD vehicles available at the time together and decided on that truck. Then I toured SW Ont. alone to find one in the colours and options we wanted, and researched the dealer cost for the truck. I waited til near the end of the month, because dealers are willing to deal then to make their month end look good, and offered them their cost, which they didn't take, so I offered them 5% over cost. I was prepared to walk away if they refused. The salesman consulted the sales manager, who consulted the owner, and they accepted.
I am sure my wife would have paid the full price if she had done the deal. (She really liked that truck).
