hey Bill, I wrote up a comparison somewhere between this car and a 53 Caribbean when I drove them both on the same day. I'll try to find it. The biggest thing with a RR is how quiet and smooth the ride is. RR was using the GM jet away 4 speed automatic and it is a god transmission. The Caribbean has a 2 speed slush box so that is one significant difference I remember.
Brand new my mom's car was 29k. It was ordered new by William McDonald the "fight promoter" based out of Miami that my dad always referred to as a mobster. His driver was a former price fighter from Worcester Massachusetts and one day he left the top down in the afternoon in Miami and you can guess what happened. Time for a new car. He ordered new RR. Always black with the PI00 headlights. Car was given to Inskip to sell and after a year of sitting on the roof parking lot my dad was the only one to go look at it. He bought the car by trading his 2 year old Caddy convertible and 5k bucks. At that point the car was barely 5 years old. I have all the Inskip paperwork which is pretty cool.
