Airfix Engineer

Airfix Engineer Mini Engine Kit

With more than 100 unique parts, Airfix Engineer is more like a learning tool than just an ornament.

Safet Satara
About Safet Satara

I do not have spare time. All there is is car time. 12 years and counting. I am a Central European gearhead, but you are probably thinking - aaa a disposable Borg drone! Well, actually, I like to dress up like James Bond too. The only thing I need to be him is an Aston Martin (and I love DBS more than DB5 because, reasons). That's something I guess.
