I have leased it with Drive Electric. Have not seen many exact figures in the forum. Does £498pm for a M3 MSM Std+ 18inch aero with 10000 free miles charging through EDF energy, sounds pricey to anyone. I have already signed the lease so at this point will not be able to go back though. One more thing regarding the referral code, the agent at the company said you will be able to add it later through the Tesla account, however now that i have Tesla account i can see that he probably was not speaking the truth and I might have missed the chance to earn 1000 free supercharger miles.
