If you have Windows you could use Microsoft spreadsheet and customize it to fit your needs.

If I kept track of the cost to resto my '88 244GL I would cry. I know that I have spent a lot of money to refurb her to almost like new condition. All I have left to do is the paint. This will be the biggest expense on the car.
I'm budgeting about 2K for a quality job by our family body man. That's with me pre-stripping the car of parts and giving him a shell.

Sometimes ignorance IS bliss.

Don't forget that time is money spent/saved.
It's still cheaper than buying a new unreliable car.

Last month I picked up my niece from my ex-brother-in-law and he said "you still have that car!" I replied "why not, she has served me well and still has a lot of life left!"
