I've the vintage and now 4000miles, superb, efficient and esay to operate. Only drawback, as I've read in a previous post, the bonnet move around 1cm toward the front after a few miles, but then quiet and safe.
I wouldn't say mine moves anything like that, maybe a couple of mm. Do you have the heavy duty woven tape on the underside of the hood, both sides and over the length at the rear?
