at first I thougt about a fiberglass roof and it is still an option that I am toying with, But if I build it I would have to make doors, add a gas heater, defrost fans and I havent seen a manx type car with a full roof that looks good ,it was never desinged to have one and allways looks out of place. I have also thought about just making a fiberglass top or having a soft top made without side panels.I am leaning twards the soft top because it will be easy to bring with and put up if I get caught in a rain storm as for heat I will just dress warm.I have started designing another car it looks alot like the new toyota land cruser this one will have doors and a roof with heat based on the same pan as this car so this one may be for sale. This one was just practice.
