I am replacing the black vegan seats with tan leather as soon as our Model 3 arrives. My wife does not want a car with black seats in the Texas Summer heat and I can't blame her. We already have a car with black seats and have to carry towels to sit on as they get so hot. Granted the Model 3 will run the A/C to keep the interior cooler than an ICE car. Already ordered the replacement leather seat covers. This is an option for anyone having problems with the seat covers that come with the car. It's not cheap, but I justified it because the tax credit will drop by 50% by the time Tesla offers another interior color option for the car we want and the replacement seat covers cost less than that plus we get a leather option.
