Try contacting the rack makers, maybe? like thule, yakima, saris to name a few. there were no racks listed for my subaru tribeca when i first got it because it was a new model at the time and they haven't been tested yet so the car model won't show up in the fit manual. i ended up getting the saris on the recommendation of my local bike shop and it worked fine. saris has since added the tribeca to their fit specs. if you get a trunk mount be sure the car is clean where the rack rests on the trunk. any grit or dirt could scratch the car and on a tesla that would be very depressing. also adding an extra cloth or thin foam piece would protect the car further. good luck in your quest.
hey- electric bike ; electric car. nice.
