Looking at buying a 110 year 2007 2.4, what are the things to look out for on thses? obvious is chassis but what other known problems?

I've owned various td5's and earlier so not new to land rover ownership.

TIA

Usual Defender things, as on the TD5, general condition of body and interior should give an idea of how it’s been looked after.
Check for play or clunking in the drive train, the splines on the gearbox output shaft can fail, with a resultant loss of drive.
Try to find one that’s been looked after. Some are used as cars and have been kept in better condition.
