Careful planning!

Following on from sound test day back in November, I bring you "all the digits day, or whatever odd people with obsessive behaviour call this.
Had to make sure I reset the trip counter at the right moment 789 miles ago and then make sure I wasn't tanking down the motorway at the time I needed to get the shot. 
Pity the temperature wasn't 5.6 degrees, but you can't win them all.
This may be the only remaining benefit of having a car that is rather long in the tooth now!
