Are you thinking about buying another vehicle?
When purchasing another vehicle the only problem with choosing one of the used cars for sale is the possible heating and cooling problems it may have. Many cars and trucks that have been previously owned tend to have a few problems with their HVAC system. This is often times caused by very poor maintenance performed on the vehicle in the past years. A lot of the times the simple fix is replacing the water pump but this is something you should have a mechanic decide and not take my personal advice.
Now, there is also a disadvantage to buying a brand new vehicle as well. The big problem with buying and new truck or SUV is the simple fact that as soon as you drive it off of the lot the value of the vehicle completely drops. This makes it worth a whole lot less if you decide to trade it in on a later date.
My best advice is to buy something used but before you pay the car dealership you should have your very own personal mechanic look at the vehicle. Just simply drive the vehicle you are thinking of buying to your mechanics shop when you take it for a test drive.
