Weeelllll, I was cleaning/organizing some crap and thought about this thread.

You know you own one when:

You keep ALL extra parts, be them suspension, engine or interior in hopes of selling them on the board.

You belong to 5-10 different boards for the above mentioned.

Some of the dents on the car are from you.

When you go to a huge annual event in Ohio with a bunch of other DSM's, you organize to see who's bringing which tools, the jack, the jack stands, the extra transfer case, the extra axles, another clutch plate/disc, extra valves, a timing belt, a timing light, oil, coolant, extra throttle body sensors, another MAF, a rear upper control arm, Tranny fluid, T-case fluid....

When you can connect the wiring harness on your engine in under 2 minutes.

When you have to tell passengers "Don't worry about the smell of gas..." or "The passenger door window doesn't work" Or "Mind the grinding/clicking/rattling".

When you are going through all your parts, realize you have doubles of EVERYTHING, and think to yourself "Man, I must be a DSMer".... Then quickly jump on the board to harvest up an old thread about "You know you own a DSM when..."
