4: Outdated Air Conditioning
The HVAC systems in our cars have changed significantly throughout the years by automakers. Using different types of Freon to limit the negative impact on the ozone. There is a good chance that you’ll have a car that hasn’t had the AC retrofitted yet. This means that doing a recharge or even getting the AC to work correctly can be downright impossible. To get these air conditioning systems into the current decade, you’ll potentially spend a fortune retrofitting.

Most consumers don’t want to go through this type of trouble to get a car cooled the proper way. A lot of potential classic car owners don’t factor this into that stellar “barn find” because a car that has been sitting outside for years is going to need some type of AC work done.
