You must have ton of miles racked up! I'm at 26,000 miles in 10 months.
Well, I did not have that many miles until this trip... I put on over 4,500 miles in 16 days of driving. That 4,500 is now 25% of my total of 18,000 miles in 18 months of ownership.
BTW, I did the 4,500 miles of driving with zero fuel costs using Superchargers and complementary destination charging!
