Even though my interest in all things moto has dwindled greatly over the last few years - it's still there - just hibernating until time and money are a little more free (if ever). With globalization and other factors, modern cars have become snap on bodies with shared platforms. I'm exaggerating a bit, but there is some truth to that. I get way more of a kick looking at older, more interesting cars. This site, Bring a Trailer, collects reader submissions of interesting vehicles found on eBay, Craigslist, and other sites. Fun to cruise though occasionally - cool site.
Related site, Throttle Yard, similar deal for motorcycles. Fun to peruse and let the two wheeled imagination wander for awhile. Modern motorcycles are fantastic - insane performance and super reliable. Still, the old stuff is more interesting to gawk at. Interesting designs, concepts, and history. Give it a go.
