I've searched the forums but have not found very much information on the African Tracks car rental company (http://www.africantracks.com). According to their website they are based out of Windhoek, are a member of CARAN and have been operating since 1998.
They have quoted me a very good rate for May of 2012 for a Hilux 4x4, but as the saying goes "if it's too good to be true, it probably is." They seem reputable and the e-mails I've exchanged with them have been prompt and professional. Does anyone have any experience with this company, either positive or negative?
