Is the Renault Megane a girls car ?

No, it's a crap car!!!

Unreliable electricals,see reliability reports on net.

Agreed. It's not particularly a woman's car (except perhaps the cabriolet models) but it is a poor buy from a build quality and reliabilty viewpoint.

The quality & reliability would concern me far more than whether or not it's perceived as a 'woman's car'.

Having said that, it is mostly women I see driving them - especially the coupé version.

My first car was a Renault Megane hatchback and I had no problems with it.

My current car is a Renault Megane Coupe and when I was buying it I asked my brother to do the buying. His reply was

"Feck sake would you not buy a Corsa or something. Bloody Meganes - women are stone mad for them and I donno why".

I still bought it..

In answer to OP's question - IMHO yes they are a womens car.
