I'm probably not getting my money's worth when it comes to the service plan cost (I paid $2k for 4 years) but part of what I am paying for is peace of mind given the new technology involved such that the amount is worth it to me. Plus, I like the relationship it has provided me with the service people. However, I'm sure if I didn't buy it there wouldn't be any real difference with the vehicle so Tesla is right when they say the car requires little maintenance. Once again, the service plan is optional. Your warranty is not voided if you don't buy it. Some of the service on an ICE isn't optional and avoiding certain service on an ICE may void your warranty.
