Well it is something i would settle before I travelled to see it so suggest you offer it with a deadline of say 3 weeks and see if he bits.

If i was buying it i would have an RS turbo/XR2i kit fitted and sprayed (cost about £200 all in) and have the mirrors colour coded, would look nice then.

Put the offer to him mate, tell him you like it but don't feel it is worth anymore than £1100 and that if he wants to do a deal then you'll bring cash and pick it up.

Don't listen to his "Been offered £1600" bollocks, if he had he would have ripped their arm off, he is just trying to recoop as much cash back as he can, if he smells money. he may bite, you've got nout to loose.
