That's one heck of a sharp trailer

I really like it but your business name is confusing. I don't believe too many people are going to get the "X3" deal.
They may just scratch their head and say, "Huh?" OR it may have the opposite effect and generate interest
Also look into the legalities of having the Maserati on your trailer. You could be breaking copy right laws

You can have the car but you can't have any symbol of Maserati showing nor the name Maserati showing. So check that out if you havn't already.
