I'm happy your car is a 62 - my comment is simply that the visible dateable features of the car match as far as I can tell a 1961 onwards SP250. We don't have an SP250 expert amongst our happy band, so this was designed to help whoever stumbled upon the page next time and/or may have been looking for diagnostic clues between the various Series of SP250.

As for why your photo is used as a comment rather than as a main photo, our system is to only use screened footage for main pictures. All supporting evidence goes as comments/thumbnails. Your photo and information are fully appreciated - I've no idea why we don't have a main photo from screened footage - any info on which episode it appeared in (number or title) in case our dedicated Heartbeat fans can track it down? Also can you give us the registration number?
