Sad news,
I suppose parts will no longer be needed at all once Vauxhall are making disposable sh1te like the rest of the PSA group.
What do you mean "once"?
I'm always slightly surprised dealers still have a parts counter at all - surely if Joe Public is buying parts, he's not bringing it to your workshop and paying labour (where the money is)..
But that is the point. Who in their sane mind would willingly pay £90 per hour in labour charges, when they can do the work themselves or get a much cheaper garage to fit the genuine parts they buy from their local Vx dealer.
I myself only use my Vx dealership dealer when I cannot be bothered / do not have the skills to do what they can do in a lovely, warm, well appointed workshop, with me getting (currently) trade prices on the work.
If the Vx dealers stopped selling the parts, then they are just handing over a lucrative part of their business to all the other parts suppliers, and even encouraging more Vx owners o take their vehicles elsewhere for repairs / maintenance.
