4s

Had a once in a lifetime "encounter" today. Noticed the car's odometer read "044443" as I was leaving the house for lunch. With some careful driving and manipulation of the accelerator pedal, I was able to get the car's digital dashboard to display the following:

Odometer: 044444
Speed: 44 km/h
Gear: 4

If only I had my camera with me ...

Anyway, I subsequently went and bought "4"D. No prizes for guessing what number I bought! General_
