I've been wanting to do the same with my datto's, I like being original, diferent. The best way I think would be to import a used car from Australia, or at least all the front section. I will do the first one sometime, get a B210, a 180B, put them in a comtainer and bring them in.
As for driving RHS, I like it, I have a RHD Jeep, it is fun, if a unwanted road companion shows on the road(like the police), I drive on the right side, away from their intrusive stares,they are on the complete opposite side, too bad for them.When going into drive throughs, when not busy(the drive th)I have fun, driving the opposite way, to the astonishment of all the people in, pretending everything is fine, and they say, you're driving the wrong way! and I reply, "you guys are drunk! you built this place completely upside down", and for the very few troublemakers or scroodges, I go, Oh! I see , discrimination , I think I will have to contact my attorneys, you should ensure access to us all, you are discriminating against me based on my driving style, watch out!(uhuhahahaha), in US people are so afraid of law suits that this stupid remark freezes them flat(ahahahaha). It is better for parking, you do not have to deal with trafic, just jump off onto the sidewalk.I like it. When a nice girl is driving next to you, you next to her, you look at her, smile, and then realize RHD is the way to go!!
