Very much just testing the water here, as I am considering a different type of toy

If I were to list this on Autotrader, what do you think is a realistic starting point?
2000 W Omega 3.0 V6 Elite Estate
Automatic Trans
MOT Sept 2009
158,000 miles
Unmarked Black Leather
CID and colour sat Nav
BOSE
Climate, Cruise, etc, Usual Elite Spec.
Good points:
Exhaust changed very recently for an Eternalcar one. Same quality as the latest release of VX exhaust, since they are no longer double skinned!
Cambelt kit done by me, 3000 miles ago.
Sonnax thrust washer, and recent ATF change.
New wishbones
Easy 30+mpg on a run.
WIM treatment less than 3,000 miles ago
Bad points:Aircon needs looking at - not cold.
Light (not deep) mark on front bumper, probably easily taken out, and some minor damage to a corner of rear bumper, but nothing to worry about.
Facelift Elite alloys will be supplied, freshly sanded and painted but will need new tyres fitting to them. Car is currently on Steels, with excellent tyres on.
Any ideas what it should be listed at? I've lost touch, so will be guided by others, if I do decide to change...
