Thanks for the advice.
I did end up ringing around, Wakefield MG had a black hs in stock. I was willing to sacrifice my original choice of colour (pearl white). It did have the red/black interior tho ?. But i was politely told its only available for private sales/finance.
Furthermore, he also added that as the hs petrol is no longer on the scheme, if i decided to cancel my order, i wouldnt be able to order a new one elsewhere.
Wouldn’t of minded the wait if i had an existing car which met requirements. Even August/Sept feels unlikely now….. ☹️
