Of course there is nothing better to a collector, (even a collector of one car), than a mint original like Paul's, next best thing is a NICE CAR that has been restored right. Not overdone, but to the quality level of factory or as close as possible. It has to start out as a nice car; "you cannot turn a pickle back into a cucumber", as they say.
People on this board own some very beautiful and valuable cars, but I have to burst anyone's bubble who believes in "perfect" cars. As I've stated previously, I used to sell them new at P/A dealership, we used to touch up nicks using the matchhead method on brand-new 911's
all the time. Even new German cars get scratched and nicked in transit, I've seen a dumb prep guy burn thru one w/ buffer-wheel, (they repainted panel and sold it), don't forget BMW's class-action suit over "new" cars w/ panels repainted at the port due to shipping damage, (panels were fading at different rates on "accident free" one owner cars). After working in Porsche organization even at final purchase level I saw some stuff that buyers would not like, to put it mildly.
Why bring this up? Just ties into the whole concours thing- one of my pet peeves, cars were made to be driven- and the illusions involved w/ so-called "perfect cars". I have nothing against REALLY NICE cars like Paul's that get driven as a second car and obviously give him a lot of enjoyment. My dad has one like that.
