"Very clean structures with subtle transition in lines. I love that you can combine this set with the Fire Station, Bank or other "city" sets. I especially like to combine it with the Superheroes "Batman" sets. My child and I really love playing with this model. I am planning to buy another set of the same to expand the station into a bigger police complex. Although, I wish that LEGO would make better looking cars for a change rather than these generic looking ones. The car in the Superheroes "Superman vs Gen. Zod" set looks good, as well as, the SWAT 4X4 truck seen in The Lego Movie set."
