Sternone,
I am only reading this thread as amusement, however, before posting figures, get out your calculator:
600-280 = 320k $
320/2(years) = 160k$/p.a.
160/365(days) = 438 $/day
438/24(hours) = 18.25 $/hour
Still a pretty sharpish rate of depreciation, but nowhere near your (shouted
) figure of $ 1600.
Now go, and play with your Mooney....
