Check that list --- I'm sure some of those 'options' were also on the '64 car --- maybe not fuel warning lights but gas gauges that accomplish the exact same thing --- more reliably. Mirrors on passenger visors shouldn't really be a huge cost or improvement --- I don't know if they were on cars in the 60's though.
185 - It's been a long time, and my memory is not great about it, but it does seem to me that my girlfriend's 68 Beatle had a low fuel red lite + guage, and a low oil pressure red light (I don't remember guage), but the lite would go out on reving it up, and also had a passenger side visor mirror. It seems to me that she was mad because it was not on the driver's side, as it was her car. I may have gotten my cars/women memories a bit mixed, but I think this is right. I remember her far more than the VW, and can still picture her lovely visage at this moment and the good times we had, and wonder what happened to her.
