I'm puzzled alongside @dfwatt about the choice of a S4 as the fun toy when you have a Performance Model 3. S4 is a great car, I wanted one, and would be up there with M3 (BMW M3 for those who don't understand heritage), GTR, etc when not in a Tesla world.
I see tons of S4's and they drive like *sugar* when I am in my Volt.
When I'm in my Model 3, those S4 drivers are very polite. Not making lots of noises.. not launching.. not weaving in and out of traffic.
Occasionally, I'll see a turn signal blink.
I think many equate fun to speed or acceleration. I don't think that's true at all. My VW GTI is one of the slowest cars i have owned, but it's the 2nd best when it comes to fun factor on the street (#1 being my E46 ZHP for those into cars). It doesn't matter if I am driving fast or slow, it's a fun car to drive. Now, it sucks driving a stick shift car in LA traffic, therefore I am considering getting a Model 3.
