That's pretty rough, driving all that way.
I sold a commodore a while back and the buyer in Melbourne, and I am in Sydney, asked me over the phone to describe it. He flew to Sydney with his girlfriend to check it out/pick it up. He said that when I drove to the train station to pick them up they didn't think it was the right car as it was too good. Obviously the ones they had seen were pretty rubbish... which is annoying as mine was in good condition but being compared against heaps of rubbish, and even then getting guys trying to knock the price down before even seeing it.
I also sold a Falcon and a guy caught a flight from somewhere in rural NSW, came and saw it, told me it was the best one he had seen and the cheapest, and then tries to bargain me down

I guess its normal to want something off the price, but when I was already one of the cheapest its not a good feeling when someone tries to bring it down further.
