Let's write down our initial mileage in 2017. Let's make a guess how many miles you will drive this year and compare with the real number when 2017 is over.
2005 ZHP : 142,460. Guess 2,500 miles
2005 Mini : 146,415. Guess 5,000 miles
2011 X3 : 65,615. Guess 24,000 miles (wife's car, her guess)
2008 Saab : 88,574. Guess 5,000 miles.
I'm also guessing one of the above vehicles will be sold in 2017.
