According to HiQ here in Worcester, towbars are only made until about 7 or 8 years after the vehicle is manufactured. Their supplier only has a Thule gooseneck and it costs R7500!

Isn't there someone here who has a 2007 RAV4 with a towbar they aren't using anymore or a scrap yard that has a 2007 RAV4 with a towbar I can buy?
