Its a John Bean 4 wheel lazer alignment machine Sure Mitz can ellaborate.
EDIT: Piccie stolen from Nurrish
Ah yeah had one of them done to mine too, cost me 80€ Strange thing though the guy working on it hadn't a clue about how and what he was doing really, just picked the model/type age and size tyres and the machine told him what to do
Not sure how good they would be then if the operator knows nothing and you come in with a set of aftermarket wheels...
