How much is a Mk1 Zs 180 saloon worth?

[XPCobra]

Theres the possibility of me having to sell the MG ( and the impreza that never made it to the road lol) in the near future so was just wondering what you lot would think i'd realistically get for my car?

If it makes any difference it has no dents AT ALL on the car, 70,000 miles, FSH, taxed till end of november and mot'd till july, and serviced less than 800 miles ago, always run on motul 300v chrono 10w40 fully synthetic oil when i've owned the car.

Extras include:
BRG metallic 3 paint
extreme spoiler
'mini' mudflaps
front and rear elctric windows
4x headrests
Pioneer X1R satnav and 6 cd changer
Parrot 3200 colour HFT kit
Janspeed rear silencer ( option available from factory?)
Sheddist clutch kit
Oil vapour catch tank
Toyo T1Rs all round
EBC redstuff ceramic brake pads all round
Motobuild springs + rear brace bar
Dipped beam and front fogs have 6000K H.I.D. conversions

Thanks
