Hi Tony
We purchased a Bailey Ranger 500/5 at the NEC and had planned to tow it with a Scenic 1.5dci 106bhp. Although we had checked with numerous car and caravan dealers and had been told that this was a suitable match when we went to discuss picking up the caravan the caravan dealer told us the Scenic would be no good. Apparently you can tow 1300kg with the scenic but this is with only the driver in the car and no additional people, luggage etc. We rang Renault direct and they confirmed this. So we're now on the look out for a new car and at the moment it looks like a Kia Carens.
It may be worth checking again.
