My 4.8 sits for weeks at a time before I'll drive it once for 20 miles or so. Then every few months I'll take it to Houston and add 500 miles to it. She's coming up on 130000 soon. I'll post a pic when it gets there.

There's a grip of maintenance (long list) that I have queued up for it, but it's been behaving so nicely that other projects keep taking precedence.
