Any ideas how long it can be with the passenger seat all the way forward etc. I need to pick up some very long radiators (but quite thin) which I want to check before I make the journey. Not near the car today so can't measure.

Thanks in advance 2011 Stornaway Grey 5.0SC Autobiography

A very rough measurement I took a while back was 7ft or 213cm to the back of the front passenger chair whilst forward. 66in or 168cm to the back of the driver's chair (at my setting).
Rear opening width: 47in or 120cm
Height: 3ft or 92cm
Again these are very rough measurements. 2012 5.0L S/C

Over 6' 3" as I've slept in the back of my RR when my tent was stolen. That's with the seat baks tilted down, if you fold the seats up you lose length but gain volume.
