So far so good! Looking at the v5 yesterday it states on mine that it's braked trailer capacity is 3.5t even though it's a manual.if you want 3.5t towing you have to have the auto , its a jap box and i like it ,its the first time i had one and i get on well with it the only other one i have driven is mates B class and its much better than that .... the latest one has had a tweek and is bit more hp , but dont think it was needed i tow at 3.5t and is plenty boss of the job
