My adive for buying a used car:
[ol]
[li]Take your time. Shop at the end of the month (or year) if possible.[/li][li]Narrow down the list of vehicles in which you are interested using research sources like consumer reports.[/li][li]If not paying cash then pre-arrange financing with your bank, credit union, parents etc.[/li][li]Monitor prices on websites like cars.com so you can get an idea of what the vehicles you are interested in are actually going for.[/li][li]Arrange for an inspection by a trusted mechanic. If you don’t have a trusted mechanic get one - the mechanic files on cartalk.com is a good source.[/li][li]Be prepared to negotiate aggresively and to walk away from a deal that’s you don’t feel good about.[/li][/ol]
This is essentially the method I used last time I bought a used truck. After about a month of looking and test driving I found the vehicle I wanted. After getting it checked out so I knew exactly what I was getting, I able to offer a aggresive but fair price. I’ve had that truck for 3 1/2 years and never anything more than minor repairs.
