Well, I went ahead and purchased the 2006 last night after a wonderful 2.5 hour wait to close on the deal. There is underspray, but looks to be only in the wheel well area which I can handle removing (or removing excess) down the road if I choose to. I got the car about $3,500 under invoice, so I would have been ponying up quite a bit of cash difference for a 2007. And based on the recent spy pics of the 2008, I wanted to get a classic 100 while I could. I thought about walking, but quickly realized there were no other comparable with 2006's or 2007's within a 1,000 mile radius.
The reason I went to the SE region to begin with was due to selection and the fact that I could locate one without AVS and that awful rear spoiler. My region (Cincinnatti region covers TN, KY, OH, MI - I live in TN) appears to equip all LCs with rear spoiler and AVS. Only way to remove the spoiler is to repaint portion of top part of vehicle, which is unacceptable or have it special ordered at who knows what price for 4-month wait. So it was either the Toyoguard package in SE or AVS/rear spoiler locally - pick my poison.
So far, loving the vehicle, pretty much night and day with the '01 Sequoia I traded.
