JN, I d say the most important thing is to find a car that has been garaged year-round and never winter driven (as in snow and salt). The elements are what ages a car . Every once an a while I see a version of a car or truck that looks like it s a time machine or something. I love them because they show what that vehicle CAN look like and there is no work involved in getting it there! I ve restored a few vehicles and it taught me what goes wrong with them- what aging really is. Only the glass stays the same . In Seattle , there s a 1999 that has had an engine grenade at 58 000 mi. BUMMER ,especially since the car looks showroom! Clearly, it has been garaged all Its life as it looks like new. This is so hard to replicate. I mean if its going to be a 2001 why not a 2001 that looks like a 2012.
something to think about ...
