I did a quite whois check and found that all single letter .Car and single number .Car domain names are now registered.

Probably not shocking to anyone but of the 40 single charter .Car domain names that have been registered, 27 were registered at Chinese registrars and 3 more appear to be owned by people in China at US registrars so 30 out of 40 are owned by Chinese domain investors.

The wholesale cost of a .Car or .Cars domain name is $2,000 a year and the retail prices vary based on registrar and the pricing you have with the registrar but seem to average around $2,500 a year.

Many single character .Cars domain names are still available as of publication and here they are:
