Other Car Rental Programs/Partners (ie. Alamo, Enterprise, Sixt) - SUV Rental in Madagascar?

I have a group of four headed to madagascar for 2+ weeks.

I see nice Nissan Patrol 4WD available through Budget and Europcar.

The Europcar offer said "Chauffeur Only".
And maybe my Accor A-club number will get me a 20% discount,
but I haven't got it to work yet.

Anybody have experience in renting in TNR ?

Thanks !
