It started 15 years ago, while I was at school. I made a short list of all the sports car (BMW , Ferrari, Lamborghini...). Then I said to myself, let's add also the sports car, GT and so on. I used a PC (it was an old McIntosh) and started a bigger list. I was collecdting magazines, so I took from there the cars. It crashes a lot of times. Every time I started again, including something more. At the end I start to put in this index all the cars in my magazines, and in the meantime my collection of books was increasing. Now I listed 40.000 models only from my books and few encyclopedias. I quit with the magazines after the Big Crash of '98! Now my magazines are thousands and I will start soon to add them in the index, because there are a lot of cars in small articles of my 1950's issues. I started collecting pictures from the web few years ago, but it was different, just a collection of weird cars. If I match the 5500 makers on my list with the 4400 of my folders, probably there are 7000 different makers! All this without considering the BIG books (like the Beaulieu Encyclopedia or the Standard Catalog) where there are thousands and thousands of entries! But I will add them all!
