Got a bit of a "reality check" last week. My 2014 Porsche Cayenne diesel with 214,000 km was assessed for trade-in value on a Macan at $20K. Paid $81K for it December 2013. Makes trading in on something else a bit of a pricey adventure. If I keep it for 3 more years, and hope that my repairs are minimal, at least my maximum depreciation is "only" $20K!!
