You might want to double check "commonwealth" countries! As for the RHD, I understood that the cars were converted in the EU. Wouldn't be the first thing a manufacturer has wasted money on. Also I'd still, if I was really interested, get a private HPI check done. A Ford dealer will only fully HPI a car that's on their books as all searches are recorded and charged for. What they've probably done is a base check which is free and can be done via data on their internal systems.
The Ford Unknown thing is rubbish and doesn't mean a thing. There are loads of cars out there the same. Not every single car had its full data inputted, trust me! None of this actually confirms this car wasn't registered new here.
Still didn't say what it was Sam, a 1 or a 2?
