Any car is a hostile environment for electronics. It's surprising that modern cars last as long as they do, in such high temperature fluctuations and dampness and condensation.
I would agree Dave but for the fact that I had three laptops during the eleven years I was living and cruising on a sailing yacht and none of them failed despite the salty tropical marine environment they were constantly in. They were only replaced to accomodate newer versions of OS. I think the use of inert metal plating on contacts played a major part in their longevity.
