First off there are at least 3 different sized cars made by Megabloks.
This is the medium Size (Same as Black Mustang, Orange McLaren, Red Nissan GTR, Blue/Red Porsche, Audi garage display set)
It will not work with the car launcher.
Cons:
Police lights knock loose easily.
Wheels and tires are difficult to change out.
Pros:
Can be built relatively quickly with any lego skills.
Changeable wheels and roof are fun for giving variety.
My 4 year old loves taking them apart and rebuilding them but sometimes needs a little help.
