Which used Renault Megane sports should I buy?
If you're more concerned about comfortable cruising than outright performance, the 1.6-litre is the way to go. However, the Cabriolet is heavier than the Coupe (because of the extra stiffening Renault added to compensate for the loss of the roof), and the 2.0-litre does a far better job of shifting it.
When the range was revised in 2000, a series of new engines was introduced. These had more power, yet drank less fuel, making them the better second-hand option
