TheAutoLog is a social network for car enthusiasts focused on each user’s car.
The San Carlos, California based site provides standard social networking features for each car, including friends, comments, bulletins, profile pages (complete with customization features) and pictures. Users can challenge other vehicles, and vote in monthly competitions.
TheAutoLog enables support for sales, with the ability to record vehicle maintenance records that can be displayed externally on sites such as eBay or Craigslist. The site also has its own for sale pages and listings for car enthusiast events/ meetups.
Membership numbers weren’t available for the page, but a quick browse established that the community is fairly deep and active.
If you spend your spare time modding or maintaining a car for show, TheAutoLog is worth a visit.
