Up until this day I have changed the following (I might add that they where changed free of charge under warranty)
1- Twice I've changed the A/C internal Blower
2- Rain Sensor
3- Steering Wheel Solenoid Lock
4- Car Battery
5- Complete Window Lifting Mechanism (Passenger Door)
6- Car Horn.
Otherwise, general comments like high internal cabin sounds while driving from the doors and console especially.
The a/c takes a while to kick in and make an effect (I doubt it will be very efficient in the Gulf area).
Brakes also make a lot of noise at low braking speeds. The ABS kicks in a bit too frequently when braking on slippery or bumpy roads.
Plastics are a little on the cheap side compared for example to a Peugeot 307.
Fuel efficiency is great on the highway at 100-120km/h.
Manual transmission is great for acceleration. 0-100km/h in about 10 seconds with no load.
Very stable on the highway at high speed. The maximum I reached was 210km/h no load and 195km/h with the car fully loaded. I think it can do better if I change the wheels and tyres to sporty ones.
Megane II Sedan offers a very comfy and spacious ride. Probably the roomiest in its class. Great Boot space too.
Generally, it is a great looking car, but some work can be done on the quality side to ensure perfection.
