I've just walked away from a deal on a used 2006 330i from a third party
used dealer.  The car was in very good shape, and $25.5k CDN$ wasn't bad
(I think) but the $300 "admin fee" which doubled when I wouldn't finance
through them was insulting.

Now I'm looking at BMW themselves, and their "Certified Series".  It looks
to me like this is very close to them being willing to treat a used car
as if it had been bought new, in terms of protection and quality and the
like.  It seems intriguing, and perhaps worth the $3k to $4k premium over
the third party dealers.

Anyone know what their "Protection Plan" encompasses?  It doesn't really
get into it, and I'm looking to avoid talking to a salesperson until I'm
set and decided.  Is it bumper-to-bumper?  Powertrain only?

I've seen warnings that the 6yr protection plan is so good that the sales
people are generally very unwilling to haggle on a price.  Does that bear
out?
