Startup Idea: Universal Search Engine for Yacht and Car Parts

Startup idea to develop a universal search engine that could simultaneously scour multiple websites (including Craigslist, eBay, and others) for specific yacht and car parts across various locations globally, thus saving significant time and efforts.

Hello, I restore yachts and there are many different sites I go to with the same exact boat, if not a similar one. The problem is that going to all these sites and i would like to be able to search the whole net for a boat or part or car for that matter.

I was always annoyed that you could only search Craigslist one location at a time, why not a similar search that includes every location. Including ebay and other sited would make it that much better, but I always had this idea that it would save so much time if only I could at least search every location around the world for a yacht or a car.
