I had a 2015 85D I traded up to a new 100D in September of 2017. Last month, my 100D was involved in an accident on the highway and has been totalled. Well, today I have come to find out my insurance company is only giving me $77,000 instead of the full value. I'm not in the position to put out another $30k, as I was intending on purchasing a Model 3 for my son. That may not happen though, because I need a car ASAP and do not want to go to the 75D because of lower range. I need the range for my commute, and with 315 miles the Model 3 is enough. I already have my invitation to configure, but I have been holding out until a dual motor/performance version. Should I get a RWD now or wait for dual motor?
