A few years ago I decided I wanted a very specific car (only 17 were ever sold in the US with the particular specs I was looking for) and the usual manual methods of searching every single car and classifieds site were too time consuming. I wrote a scraper to check them daily and generate a report of the new results. Six months later I found the perfect one, flew out to pick it up, and had an epic 1,300 mile roadtrip home.
