Fortunately not, at least for truck identification (I don't know how reliable was his car knowledge). He was good at generic identification, but the details and complements he gave (ton-rating, model codes and so on), even if possible, were nothing more than guesses: how can one identify a ton-rating when several trucks share all specs except the said ton-rating or a wheelbase when just the front face is visible?
There's still a lot of corrections to be done on most of his contributions...

He stopped contributing in 2013.
