+1 for the Ferrari comment!
Leave the classics alone as their milage does not count that much.
For the new ones I can clearly tell that the first thing I don`t miss - is the engine sound.
Just returned from a short trip to Styria with the e-tron. Must say, it´s perfect comfort.
My son (15) choose to take the e-tron instead of the Morgan as he feared possible rain;)
