To be honest, if I was driving 9,000 km I wouldn't go in any of those @keithboone. I'd want something more comfortable and, yes, more economical.

For a couple of hundred K little jaunt I'd go for the 1956 T-Bird convertible.

And just driving around the car park and getting in and out of it would keep me happy if I was in the 1955 gull-wing Mercedes. 😁
