This may have been discussed before but I've only just joined the forum, so apologies. We own a K12 - 1.2 auto - on a 54 reg plate. Lovely little motor. We live in London, within the North / South Circular zone. I don't know the car's engine rating (Euro 3 or 4?) and I'm getting conflicting information about whether or not we'll be 'legal' when the extended ULEZ zone kicks in. When I enter our reg number on the ULEZ site it says we're OK but according to posts I've read elsewhere we don't pass the test due to the age of the car. Sorry if you've already done this to death but does anyone know what's going on?
