We play music for a living.
We are 12 years in and have driven 500-550k miles.
For 10 years, we did 30-40k on a mini van and 15-20k on a pickup truck, towing an RV. ($8000 a year in fuel btw)
Now we just drive the pickup about 30k miles a year. Cut down on the people in the band :)
Basically we bought a mini van with 126k miles on it in 2006. 5 years later it had 303k on it. 177,000 miles in 5 years.
It was a huge relief to "only" drive 29,600 miles last year.
