I think to control spending is why people have become more interested in maintain the PETINA of and old car, truck, motorcycle instead of doing 100 point restorations.
I don't necessarily think so...the rustic "distressed" look is very popular, look at all the EXTRA money people spend to buy NEW clothes, NEW furniture, vintage cars and other junk that "looks" old. It more about personal taste and style. In many situations people are spending more money on cars with a interesting petina over a perfectly restored car or even creating their own faux petina on their vehicles
