I’m going but not in my Caterham, I’m taking my van this time with a caravan in tow. Are you going with someone in the passenger seat? The toll pay stations are on the passenger side so if you’re on your own you’ll be getting in and out
A better idea might be to avoid toll roads on the way down if you can. French roads aren't usually crowded although the police take a lot more interest in speeding etc, over the Le Mans week.
If you're going in the 7 for pete's sake don' go on the autoroutes! The french D roads are really good, and the reception you'll get from the locals in the towns and villages is great
A load of us are going down in 7s to the Classic this year
