And it has opening doors

Unfortunately, the doors left no room for the exhaust. Tradeoffs, right?

Concerning the typical Maxine outfit I suggest some black acrylic color to customize the doll.
I haven't tried any minifig customization yet, but it may be time. How does acrylic paint bond to the LEGO plastic? My experience (although not recent) has been that acrylic paints have a tendency to flake off after a while, and these are likely to have at least moderate use by small kids.

Hopefully Maxine and Max will meet on the highway. And hopefully they won't be like cat and dog!
Agreed! Although some cats and dogs get along fine together!
