interior might just look good from the recent valet? it's quite easy to make leather seats temporarily look much better than they are using leather treatments. although if it's been owned by skinny folk who get into the car carefully then the bolsters don't get scuffed as much. likewise the paintwork, silver grey will hide the scratches, especially if it's just been treated with products. i guess the car is looking its best for sale, which is no bad thing. a new hood (if bmw supplied) would be a big plus for me if looking at a roadster. i thought the front grills were just odd due to shadow effect on the pics, he does state it's taken with a phone. easy one to clarify though.
i think location and desire to sell are both influencing the price. i bought a z3mr from cornwall and factored that into my negotiation. it's certainly worth a look at that price.
