Best of British :: Cars :: About
This site is the result of a programming exercise. It provides
a central location to look for (British) classic and high
performance cars currently for sale.
Each ad is analyzed individually against a database containing
more than the makes and models found on normal car sites. Try
looking for a Super Seven
(using the category) and you'll be surprised how many different
makes there are. The make and model detection is supported in
the quick search box as well – How about searching for a
Lotus Esprit Turbo?
This site offers (at least) these advantages:
- Car categories to identify car genres, e.g. Super Seven or Cobra.
- Detailed car makes and models.
- Cars which are offered on several platforms are aggregated into a single entry providing links to each individual ad.
- Car prices are automatically converted to €, mileages to Kilometers.
- The prices and even the price refiners are calculated based on today's currency exchange rates.
- The search result page also offers links to manufacturer home pages, car enthusiast clubs, and Wikipedia pages.
- Search index contents are based on a number of used car platforms *
- The index is updated on a daily basis.
* Only platforms which permit crawling (based on robots.txt).
