As you say,2nd hand car transporter are only slightly cheaper than a new one.I got a Brian James Clubman,with a tyre rack for 4 extra wheels and a storage box for 2 jerry cans.Best money I ever spent.Tows like a dream at 70mph (yes I know thats over the speed limit),is well built and its lite up like a Christmas treee at night with side marker lights and all.
