Hi, I am currently in the process of buying a used Model Y 22 7-seater with approximately 17,000 miles and the Full Self-Driving (FSD) option for a price of $55,000. I am hoping to negotiate a little bit more, possibly $1,000 or $1,500. Do you believe this is a good deal or should I wait until March(HW4 news, Tesla Vision stuff, V11, and what not?) to make a purchase? The reason I am not considering a current vehicle is due to the lack of parking assist features for FSD vehicles, which is a disappointment for me.
