Valid point,
As with my classic cars, I found a relatively easy solution to counter this. I select less-than-perfect samples for testing, target practice and general fun. I have a daily driver that has some blemishes, so I don't have a heart attack when my retarded neighbor bumps into it (as he did last week) and I keep the good cars in the garage/workshop.
I do try to keep things matched though. When I take the S/42 to the range, I'll transport it in a Mercedes with black leather interior so the leatherwork matches. But when I take the LP08 with it's light brown leather rig, I take the 300SL with light brown leather interior. Am looking for a green ribbed velours holster for the other car, though
