The Mk3 Megane is so more refined than the previous models(which I have driven). Renault really got the styling right on this model too. Lux has climate, cruise control, aux, Bluetooth etc etc so all the creature comforts. Car is a breeze in traffic compared to 172/182 on which the clutch can be quite heavy. I have used both a 172 and 182 as a daily too.
I am biased, however it took me ages to find mine and I absolutely love it. There are many other cars I looked at buying too in the price range. You don't see that many Meganes on the roads either. The one you have been offered is almost the perfect spec and in a desirable colour. I am sure once you go for a test drive it will answer all the things you are slightly unsure about. Then I look forward to seeing some pictures ?
