Day trip to Paris from Normandy - Best way?

[IROC-Z]

Just booked a short break in Normandy in late October and amongst other things we fancy doing a day trip to Paris. I naturally assumed the train from Rouen would be the easiest method, but the information sheet for our 'Gite' says it's possible to drive to a place called Porte Maillot on the outskirts and park and then get the Metro in to the city. According to Google maps this is around 2hrs drive from where we will be staying.

Is this insane? If we are actually avoiding the very centre is it viable to do this or will we spend eternity in the car in some awful French traffic jam being forced to listen to French radio stations? I've done some research and there does appear to be a couple of large Vinci 24hr car parks near the Metro station.

Merci!

There is no reason to drive in to Paris beyond the Peripherique. Park someone around PM or the laughably named 'La Defense' (only at weekend - it's the main business district).

OK thanks! What I was getting at was that I've only heard horror stories about Paris traffic, and I didn't know whether attempting to get anywhere near it was a bad idea. PM or La Défense it is!
