i sold a mint condition painted one for 35 posted so id say around 20-30 if your collecting it and £20 for the pair of ph2 rear lights.
All easy jobs the rear lights is one wing nut each and change the wiring, also get the plug with about 6 inch of wiring too as you need to splice this to your old loom real easy there is a guide in the guides section, and as for the spoiler just bolts off/on.
