$42k isn’t cheap, Tesla offered me a new 50 mile inventory LR AWD red/White EAP 19’s for $51k, so a used RWD should be much less because new also gets tax credits. There are new ones to be had with discounts, just talk to a sales person. The asking prices for used are often crazy. There are so many people looking to sell 2018’s you should be able to get a deal.
