I can give you a preview. My 323i packed it in after 14 years and $30,000 in service and repairs. I loved that car right up to the day I towed to the recycler for the $3,000 scrap-it rebate.

So far, after 2 years and 60,000 km, my Nissan LEAF costs $1,000 less in service and has saved me about $6,000 in gas.  Mostly because regenerative braking has doubled the life of my pads & rotors,  no oil & filter changes, no camshaft sensors or clutch bushings.
