This sheet is for my Audi, which I only just got, so it lacks a 
few features, which I'll explain. I have another one but that is 
for my Trabant and some things are only relevant for 
two-strokes.

When given my first car in 1977, I was also taught to keep a 
ledger of all expenses. I am still using a small exercise book 
for that, the sheet is just an addition. This explains some of 
the ideosyncracies. The smaller sheet is kept on my LX and the 
entries are deleted every time I turn a new page. It calculates 
consumption, page averages and help me enter prices when 
travelling. There used to be French, Belgian and Netherlands 
money, now only British is left.

The bigger sheet is the main one. I use it in a 123 clone on my 
Atari. Thus I have crisp black on white instead of that nasty 
grey on grey and more than 80 by 25 characters. I am also able 
to have two windows that overlap nearly completely, i.e. both 
are big and I can switch between them.
Comments (like Autobahn, top speed or snow and ice or trailer) 
and explanations are in the ledger only. So prices for repairs 
and maintenence (everything being caused by use) and fixed cost 
(everything occuring even if not driven at all, tax, insurance, 
devaluation) are just eneterd into the columns of the sheet from 
the top of the page. The entries begin at line 19. When I reach 
the bottom of the page in the ledger I mark all lines with 
entries (i.e. 19 to 26, note that in this case this would leave 
out one entry in clumn "fix", which will not happen when I 
really reacht the bottom) and insert that number of new lines. I 
then copy those lines into the gap as values (formulae take a 
lot time recalulating) and deletze them by copying an unused 
lower line (e.g. 28) over them and then continue with the new 
page.
The statistics are reached by <F5><Pos1>. Nearly all cells are 
protected. A statistic over the current page, which may contain 
one or even zero fillups, is meaningless, this I keep two. One 
is overall the other is over the current page and the previous 
one, typically spanning about one year. Thus three values have 
to be updated here: The last line of the previous page, the last 
line of the page before that and the last line of the whole 
sheet. Repairs and maintenance are typically between 50 % and 
100 % of petrol in the longer run - nice to know for people who 
don't keep a ledger. New cars are less of course, but then they 
lose half their value in two years.

I'm not in the mood to explain more and still maintain, that 
building a sheet from scratch yourself is easier than trying to 
understand mine.
