He's also free to join and use Zcar.com. I'm the mod there. It helps if he will read the sticky about cars for sale and follow the directions.
As far as I'm concerned, all the Z-car sites need to play nicely together.
BTW - I moved from Washington state to Texas, and from there to Colorado. Definitely different subcultures, although WA and CO are very similar. TX is a different culture - from the South, modified to the Southwest, and the customs and politics are quite different. I lived in College Station, TX (university town, home of Texas A&M, which is a quasi-military college) and when people moved into town, especially from northern states, I used to ask them "how far back in history have you just moved?" The average answer was they felt like they had moved back 20 years.
I met a lot of super people in TX, and built some great friendships. It's a fascinating state with stories and history around every turn. But in the 13 years I lived there, I never felt like I was really "in place" culturally. I am much more comfortable in CO.
