I think its very difficult to use such a boolean classification for a reletively recent car. It is often said that the last of the mechanical BMW's was the e46/e39, I wouldn't agree with that, the amount of dynamic calculations going on in either at any given moment is staggering.

I've had loads of mechanical cars and I hated them, fault finding was a pain in the ass, anything wrong with modern cars usually requires moments to diagnose if you have the right equipment. Not to mention the mechanical cars are comparatively slow, ineffeciant, unrefined. I had a few Mk2 GTI's and you wouldn't dare go anywhere without an array of tools in the boot.

Electronics and computers are put in cars to make life easier, they do exactly that, in most cases do it very well and make life easier for the people working on them. Cars are getting better and better, its all down to the advent of electronics in cars and the ever improving sophistication of the systems they use.
