I dread to think of the cost of routine maintenance on such a setup a year out of warranty.
The idea of technology from $70,000 cars in $30,000 cars is always "cool" - until the reality of maintaining such drivetrains is driven home (pun intended).
With the economyin the crapper, the sheer volume of sales taht used to drive the cost of the big 3 spares down will no longer apply.
You ever seen the look on the face of a 15 year old BMW owner when the repair bill of their $4000 car is the same as the bill on their cousins new $80,000 Bimmer?
