Seen this before, where someone claiming to be advertising an item and not actually selling so there’s no point in bidding. Not sure how this works other than maybe working as click bait to garner more interest?
On a side note, I’ve driven one of these & found it very uncomfortable, the steering/seat/pedals don’t line up so you sort of drive it twisted... very weird...
That was Dec's, it went to either a vauxhall dealership, or an owner with connections to them, in Ireland if I remember right!
Also I've likely said this before, but I remember your username from the vectra owners forum too, there's a few ex modified vauxhall owners on here and some that aren't, but are back on mtbs these days
