This, for me is terrible news, I don't have a database of obscure cars or an extensive library and 90% of the puzzles I have solved have been found by searching the internet, the search is often much more rewarding than the point gained by solving the puzzle, I'm sure most of you here have been on a 'voyage of discovery' by trying to identify a car online and then going off at a tangent discovering a previously unknown world of cars, i.e. (for me anyway) American sportscars of the 50s or French Barquettes.
I'm not sure what the answer to this is, does the Google tool still work if the photo is heavily cropped, or changed from colour to b&w?
Otto, I don't think you have to feel any shame, and your self inflicted penalties are very harsh, if I had discovered the Google tool I think I would have used it for a while too before realising that it's taking the fun and interest out of the puzzles, and that's what Autopuzzles is all about.
Damn you Google!
