Not going to lie I went back and forth on both as well, and there was a Mach E just sitting at the local ford dealer for the taking, ultimately decided on the Tesla for the same reason the charging network. Though my girlfriend is now heavily interested in the Mach E (she has bought Fords her entire life, so she is drawn to it). Though I do have a friend who works in Ford's engineering team and is not happy with me for not picking the Mach E.No change in EDD. Still 10/20-11/9.
In other news, a Ford dealer called me with a Mach E offer which he was originally selling for MSRP + 2 k. They've now dropped the price to MSRP. It's a sign that demand is moderating. I still turned it down because I have decided to wait for my model Y. For a long time I was equally drawn to both cars. But now I have been turned around by thinking long and hard about the supercharging network and the advantages it offers versus the $7500 tax credit.
Having said that, having test driven both cars extensively, I do think the Mach E is the first credible competitor to the Tesla. It's a great car.
