Mate if you're talking performance, then a 530 will not see what way the 450H has gone lol!!! We compared the E class 3.5D, 530D and XF Jag and surprisingly there MPG was not that different. The E class I drove had managed an average of 39mpg over it's 9000 mile life, poor! the 530 was not much better and the XF was awful!!! I hated that motor.....
I love the stealth attached to the GS, and the real world running costs for a 350bhp V6 are very very good imo!
Just wish it had more room in the boot, but you can fit 2 sets of clubs in ;)
When driving on sport settings on both gearbox and suspension etc, there's not a lot like it!!! Just need to get the Yoko's changed for something a little better......
Ours is a '58 SEL which was a smidge under 30K last January, a real bargain for the performance imo. Going into London is free and the tax bill is funny for such a big motor!!
I took 4 of us to the Haye vs Harrision fight in Manchester last month, 4 fat lads ;) no complaints and no fuss at all...
Good luck shopping :D :D
PS - Just don't tell to many people about how good they are eh, I don't like to see to many on the roads lol ;)
