The older I get the less I enjoy any of it, other than driving. Through my teens and twenties I did everything from engine swaps to transmission rebuilds in my backyard under a Costco canvas tent... now in my thirties--I am quite happy to pay someone to come to my house to detail it once a month and pay someone to change my oil. I do wonder if all the years of working on "old" cars burned me out on car maintenance in general...
