With respect to all other opinions,

Renault quality are built same as any other car. It is being sold in less amount because there are lots of competition, secondly, if you can see their motto recently: Everyone can make an electric car, But who can make an electric car affordable to everyone?
With regards to spare parts, it may seem that the spare parts are expensive as they claim from their own experience, but reality is, it is the same compared with its allied Nissan. What makes them thinks it is expensive? resale value. You can sell your tiida 2007 for 30,000qr but you can only sell your clio of the same year model for maximun of 15,000. Why? it is because Nissan is more known here in qatar compared with Renault. Lets go back with the parts, same part for both brand has the same amount, but the Renault customer will complain it is expensive because, he has only bought the car for a very less amount. Got it? Personally, I don't care about the resale value as long as I driving the car brand that i want. Goodluck on your choice!
