ARD, I'm not sure if you are purposefully being condescending, but I'll give you the benefit of the doubt you are actually trying to be helpful. To answer your questions, I have posted on another forum and searched the net. Sometimes a word of mouth endorsement from a few satisfied/unsatisfied customers is better than any Dinan/BMW dealer propaganda or review from a automagazine.

"The benefit that Dinan has is that they have an insurance policy they can rely on, but if BMW and Dinan get into a pissing match, you are in the middle." I have brought this issue up before on another thread.
