Where indeed would it stop Chris. Rumcars was set up I believe to cater for the needs of rare microcars that didnt have a one make owners club, Reliants, bugs trikings, JZRs DRK's etc, all have there own clubs and registers, others of the vehicles mentioned come under kit cars, invalid carraiges have Stuarts club and for the electric vehicles there is the Battery Vehicle society which is excellent! They may not be your cup of tea Chris but lets just worry rare microcars.
