That'll get ya started, but notice the short stem / seat cocked back / chain guide. Check her over really good for damage. She's been a jumper.
Also, since there's no front derailleur you will be limited on the trails you can climb. I don't use my granny too much, but there are a couple sections on my local trail that I have to granny it up with me sitting or leaning back when it's muddy or I'll spin out and have to walk it up.
I hate walking up a trail...it makes me feel like less of a man. Even less than I already am. The bike is cool though. It would make me feel like more of a man if I could have it. Please buy it for me.
Check for cracks in all of the weld joints. Check the handlebars where they meet the stem. Check the fork legs and dropouts. (It's not a 20mm, right? I didn't look to closely and I'm too lazy to go back to look)
Just look it over for damage, ride it around a bit, buy it, and send it to me.
