Having given up the idea of towing our Smart4two due to the price of connecting it, we’ve just had a good price for the labour-only element of fitting an A-frame. However, we would have to provide the A frame ourselves. The engineer said we might even find one secondhand to save a few pennies. May I ask (a) what sort of A frame Funsters would recommend for a 2012 Smart car? We would prefer lightweight. And (b) how would you feel about using a secondhand one? Is it likely to be a false economy? Many thanks. Pen
