Check for rusty rear chassis
If it has ace, check rams and pipes for leaks.
Check the abs tracktion control and hill decent lights all light up with ignition on then go out once started.
check for since of water ingress from sunroofs.
check for knocks and bangs on test drive, If it does it mite just be anti roll bar bushes or could be engine mounts (in from front) or watts bushes (from rear) bit harder, Not worth walking away from just knock em down.
And if you find a basic one but in good nick remember you can add stuff easy so mite still be worth thinking about, ie cruise control, heated front windscreen, I think sunroofs con also be convert from manual to eleectric.
