Back in 2000 I bought a new Ford Focus. Bought via an internet importing “dealer” as that was an available method back then.
I ordered a full uk spec (RHD) with colour/extras as I would through a Ford dealer. It came from a Ford dealer in Ostend, delivered by trailer to the door, taxed. I saved Over £2500 on the deal that included all costs. Never had any issues with dealer servicing. The only very minor downside was when I went to get genuine Ford spares as the car didn’t show up on the dealer database. There were great people in the dealership and never had any problems.
My only reservation with buying unseen via the internet now would be sorting out problems that might crop up. Who is liable as the seller? The dealership the car came from or the online agent? It would be interesting to see the legalities, probably encompassed by t&c’s.
