I haven't toweed the VX but have had the horrible experience of towing a miata on a two wheeler with the gear stick in first and wondering why I couldn't get up to 50 on the freeway.
I would assume the trans oil would boil in a VX just like it did in the Miata, real smelly and lotsa smoke, Oh did I mention expensive too.
Go ahead tow it but keep looking over yer shoulder for the tell tale clouds of smoke!!
