Purely a non-scientific observation...but it seems like 100-Series resale values (actually sold) have risen a little over the past 1 to 1-1/2 years.
I would have said the opposite based upon the people I've known/seen who've bought one. It does seem like the advertised prices have gone up, but I think that phenomena is linked to the overall escalation in used car prices this year with the soft economy and a lack of supply in the used car market.
