Hi Michael
Before I took up caravanning 2 years ago I had a 307. It was a great car. We bought a Abbey GTS Vogue 212 and the 307 pulled ok. As we agreed that we would go regularly we traded it for an X Trail and a bigger van. Still got the Witter bar & Alko stabiliser in the garage gathering dust. Getting back to the point though, as a novice at the time it seemed to just about have enough power.
Hope this helps.
Dave
