I dont like the i7 either but have to say, to my eyes all Merc EV:s look much worse. They look so fat and round, horrible designs. The i4 looks very decent when you see it live and the new iX1 is a nice design. I have yet to see a nice looking Merc EV.
My brother in law has a Panamera E-hybrid 2018 and I really like his car. Its responsive and turns very well for a big car. There is quite a difference to the Taycan though, which we both agreed on. I have a 4S with PB+, no RWS but otherwise nicely specced. It feels smaller and more agile than...
Mustang interior better built quality? Hard / impossible to believe. In 40 years of car ownerships I have never had a car with the Taycan interior built quality. Mostly BMW:s. Zero rattles in the Taycan, no sounds, nothing. Only minus is the leather wear on the left seat side bolster.

If you mean a G82 Comp, I am sorry I don't believe you. Even the rwd version has done 11.6 1/4 mile times. F80 yes my 4S is faster but not faster than the G80 Comp at least not in the rolling race. The awd G80 will beat a 4S easily in the 1/4 mile. Those engines are monsters.
