Getting fed up of high-perf , being happy with less
I'm only 71, and my HO 367 is stone-axe reliable, goes 93 in the Eighth. It is now old and tired and rusty as heck, so I don't drive it much anymore. However, I would still not be afraid to drive it anywhere as I have in the past. It was built in 1999, and all bugged out by 2004, and now only requires regular maintenance.
However, I too am changing. The thrill of hammering thru the gears, and driving like an idiot, is not like it once was. That part of my life is pretty-much over.
I imagine that when I hit 78, I'll be happy to still be walking. But, you know, there's always bumper cars ...............
