Hi there,
Well I tow my 2005 Lunar Clubman with an Alfa 147 JTD 16V (140) so it has the same engine and is of very similar weight. The underpinnings are different though, but even still, it's worth noting that the 147 is a stonking towcar with plenty of get up and go and handling to match. I have covered 100,000 miles in mine now and I do alot of towing from Essex to the north of England and Scotland so it's proven its worth on many occasions.
I suspect the Bravo will be very good with similar dimensions and short rear overhang, it should be great!
