I see that the OP isn't maintaining this Guide regularly any more but I'd like to pose a suggestion regardless.
I think a problem under the "KNOWN ISSUES & RED FLAGS" section is in order to warn about the ABS Power Brake Pump Master Cylinder Booster Assembly leak/failure issue and the approximate cost of the repair, common in the 2000-2002 T4Rs. As these vehicles are now reaching an average age of 180,000+ miles (probably higher) I am seeing more complaints about this issue across many automotive forums. Its a $1200 part (OEM) and 5-hour shop time charge, costs that could be the deciding factor between a purchase or "walk away".
My recently purchased T4R's assembly is leaking. Had I known to look for this I probably would have passed on the purchase, despite the great price.
Just my $.02
