same, parents have a Megane III 1.5dCi 106 Dynamique. Looks very nice in my opinion, when parked next to my Megane II, it makes it look dated (obviously!)
A few things I've come to realise though:
- Front passenger door shuts correctly, but stands proud of other bodywork by about 5mm. VERY noticeable - almost looks like the door hasn't been shut properly. Hopefully just needs an adjustment but this isn't the point.
- Front door grab handles - they squeak when you pull them to close the door and do not feel sturdy at all. Even the Megane II ones feel 10 times better. One of the first impressions a person will get after getting into the car and closing the door.. is a poor quality grab handle. Are Renault really trying to improve quality?
- Even though the boot is bigger in the Megane III, every other storage compartment is smaller than the Megane II.... centre armrest, glovebox, underfloor storage, the storage areas in the door... all smaller. Front doors no longer have the lidded compartment, near the electric window switches. Dynamique trim also loses out on the rear centre armrest now.
- Even though it is a nice place to sit in and quality and fit & finish look nice and high, prod around - I fear a slippery slope downhill soon after ownership.. just like the Megane II. (Remember when you first got your Megane II, thought it was really well built and all, and now.... you realise it's very fragile?

)
At the end of the day, I really like the Megane III and I would go as far as getting one myself, but I would get one because I like it and for it's desirability, not quality & reliability. Get a VW Golf Mark 6 for that!
