Stay away from Renault the is a thread here on mybb, someone was complaining that he/she has to pay R16000 to replace cambelt. If I remember correctly the car is going for 90000km service so please stay away from Renault.
Another car that comes to my mind underrated, nissian Micra just like Honda brio it's ugly but reliable little car.
Honda Brio fuel usage fuel tank (35 litre) give me close to 600km. I am happy with the car I have 2014 model, I want to get 2016 facelift. Service at the dealer R2500 including labour, material cost less than R1000 plus labour hourly rate of R730. So I'm sure at independent workshop it will be cheap.
