Your cashback is based on distance travelled for the month, so if you do only 500km then your not going to get your full cashback - they also cap it at a certain amount which is usually 2200km pm.
They have a very strict admin process and rely on people screwing up to not make payments to them.
Things like charging R500 if you forget your FTP password to upload your photos of your car - you need to take photos of the speedometer and the outside of the car each month on a specific date.
If the signage is damaged or faded, you have to pay for it else no cash back.
At anytime they can withdraw this system - ouch.
They can advertised anything on your car - that could be really embarrassing if its a political party or female hygiene products
Some of the cars come without warranty and are demos.
And yes, I looked into the system and decided to walk away.
