Shell has this Lego promo since late this year. There are I think five racing cars, one truck, and a set of a chemist, race car driver, and what I think is a mechanic. So far, I have the latter, the truck, and Ferrari 150° Italia. I only wanted the characters set and truck, but I am now tempted to complete them all. I still have until the end of the month. *crosses fingers*
Today I got the F4. I think I only two more to collect.
