Many thanks for all the ideas/points of view .. even if some of them don't fit the "specification" .....
Just to continue the research so far .. and working on petrol only ... as I don't have a ship licence ...
BMW ... only the 7 series, and from 735i upwards... weight 1860kg everything else is too light unless you go for the 535 GT option ... not sure the hatchback would work with the amount of kit I carry in the boot, and LPG would certainly not work with a hatchback
Mercedes ... only the S series s350 upwards weight 1840 kgs everything else too light
Jaguar XF .. most are 1635 kgs .. too light until V8 at 1780 kgs (nearly 1800 ...
)
Jaguar XJ .... all diesel until the 5.0 V8 @ 1892 kgs
Audi everything A7 and below max at 1740 kgs, so left with A8 3.0 TFSI 1830 Kgs
Lexus LS ... start at 1830 kgs but prices are stupid and very few 2014 ish around
can't think of any other rear / 4 wheel drive saloons .. can you .... ?
