I try to. I ALWAYS check the dealer after I have traded something in to see how long it sits and what they end up listing it for.
I'm curious what happened to the 3GS that I had that was totaled. It was in great shape, before the wreck, and I'm sure someone took it and tried to fix it.
Any other Lexus we have had are still registered under our Lexus.com service accounts, so anytime they take them in for service, I can see that.
