The link to last year's ad is irrelevent. Almost certainly the car has been with a different owner for the last 12 months. From the YouTube video it appears that the bodywork issues have been addressed. Not much info on e bay but I'm sure a PM to the owner (on here) would get you some details.
A couple of things I don't get. Why is a car dismissed as a bad buy because it's been for sale before ? Times are hard, running a second car or one 3 litre is not easy these days. There could be a hundred other reasons the car is for sale again not related to the car condition.
The other thing, why the obsession with mileage. This car has had its price adjusted to account for it. Use it as a weekend car and others will catch up.
At the price it's definitely worth looking at if you are after a V6 GTV.
