This section provides some answers on questions you might have:
Determining if a car featured in one ad is the same as the one in another ad is not as simple as it seems. Comparing images is simple for the human brain, but there's no simple computer algorithm yet. Each ad is assigned a key which consists of several ad properties. Only ads with the same key are considered equal – if only one of the properties differs, is missing, or was misinterpreted, the whole key is different.
Some ad providers do not allow crawling of their site (robots.txt or "meta robots" directives). If you would like them indexed, feel free to contact the ad providers asking them for crawling permission. The more requests they receive, the more they might be willing to allow crawling.
Just like the Pistonheads classifieds section boring stuff, I'm not interested in mass market car makes. This is the reason why you won't find any BMW, Audi, or Mercedes on this site. Although I quite like the Z3 Coupe and the Smart Roadster...
If no price is specified or can be found for a car, it is usually advertised as Price on Application (POA).
Drop me a note on firstname.lastname@example.org with the URL you'd like indexed. I'll have a look at it and get back to you.
I'd love to, but as things are, this site is only a hobby and a playground for search engine technology.
