Value of Stock vs. Modified to Increase Driveability

The market on classic cars especially muscle cars and especially mopars is still pretty hot. It will always be tied to the economy somewhat because these are not essential and as wrenching oriented buyers continue to age and the new generation grows up on instant gratification I have to believe that the market will get even tighter. But as the second owner of a 1970 340 swinger that I have continued to improve my car myself direction has been to keep as much of the interior and exterior stock appearing and do upgrades that don't include anything that a new buyer may want to change back to stock form. But I also totally agree your car your choice but I would add your opinion may change over time and what seems like a really good idea today may make you scratch your head later.
