VRT relief for EV's imported from Northern Ireland

I didn't realise, I could get a third party to do up a Sad, many garages up North point blank won't supply them, or simply have not heard of Tss or Sad. I'm of the opinion that Ni cars advertised as Vrt ready.. Ie on a Ni plate or can supply a sad do, might sell for a higher price, because they have a larger captive audience

Thanks I contacted a customs clearance agent, I explained why I would need a SAD document . they mentioned "a SAD doc is an indicator duty and VAT has been paid at point of entry if for example a dealer in NI imports a car from mainland UK. They also mentioned if the dealer has no intention of selling the car to ROI, they therefore do not need to pay Duty and Vat, and therefore there wont be a SAD doc

If however the dealer , does intend to sell the car to ROI, then duty and Vat would need to be paid by the dealer , and hence a SAD could be issued "

Are they correct ?

I assume if they do this (pay NI VAT at point of entry) they can claim back English VAT?
Or am I misuderstanding

I am in a similar situation with saltmarine. Did they charged any amount for SAD certificate? They are asking £500 for me to get a SAD certificate.

Anyone ever use this crowd? https://www.ukcarimports.ie/ Been looking for a Skoda Enyaq from the North but in short supply so was having a look but don't know anything about them

I wonder is feasible for a customer to get the reg , contact a customs agent, and get a SAD

In addition the CR Morrow car prices are usually a little lower than SaltMarine
