So I’m seriously considering purchasing a 2018 model S p100d with 6000 miles on it..The car is in pristine condition I realize there are some variables that would dictate price but what would be a general target? I generally don’t keep cars for an extended period of time and I really only want to buy it if I’m getting a great deal (as anybody would I’m sure) any help would be appreciated I’m new to the Tesla community ..
