I'm trying to figure out if the service plan is worth it for me. I bought a 90D about 5 weeks ago. Expected mileage, even with the "Tesla bump", is only about 6-7k a year (I work from home and don't drive a lot). Also, it's pretty likely that I will upgrade to the latest & greatest in 3 years, so buying anything more than a 3-year contract may not make sense. Given these variables, is there any reason to get the plan? Would I even need the 12,500/1-year service at the end of year one, since I'm only driving about half those miles? Which parts of the service (if any) are based on time, and which are based on miles driven?
