<<You ARE going to have evaporator problems, you ARE going to have to pay the 15-19 hr labor to fix it, you ARE going to have the head gasket problem, and you ARE going to have the wiring problem.....>>
Knowing these faults before-hand makes one a smart buyer.
But consider that the E320 is now becoming of age that many have had these problems early on and they have already been taken care of.
Wire harness and head gaskets more so than evaporators...
So, if a service history search shows these repairs, this is a good solid car well worth the going market.
