The 4.4 from 2006+ is the Jag unit also the 4.2 S/C from 2006 is the Jag motor.
Engine is bombproof you need flashlube for the LPG system
@ukadamwest has a 4.2 on LPG and it runs well.
Basically anything inbetween both front and rear bumpers is an issue
Parts are about the same price wise as the D3/4
Watch out for rust around the rear rear arch around the secondary rubber seal, dirt and sħit finds its way and sits there, evntually eroding away the paint then the metal etc
Watch out also around the rear Seatbelt anchorage point and the rear subframe mounting area..
L322's aren't shy to rust, especially neglected ones.
Leather on the seats is quite thin the bolsters can wear through, especially where the piping is around the seats.
The Coolant Valley pipe can/will let go eventually on the AJV8 it's only real gripe, it's a 45min job on the N/A and a 4-6 hour job on the S/C
Watch for water in the boot, this'll affect the electrical components. - wheel well in the back is a good clue.
On and the seating position is not briliiant is you're over 6ft.
Weirdly if below it's rather comfy, i'm 6"2 so not too bad but after a while you suffer
friend of mine is 5"9 and finds it very comfy
