"them"?
I was only kind of kidding about more than one at a time. I mean, if something comes along that's a must-have at the right price I might try to buy it, then sell my 2005, but right now there's nothing on the market that meets my specs better than my current 2005 E350 V10 4WD RB50.
Meanwhile, I do have some observations about the previous rig (all good) that I want to bring up. I'm trying to carve out the time. It will happen shortly.
