“The value in the set is clearly for those who already own other LEGO City sets. Even with that in mind, I think LEGO could have done a better job of including more value in the set. I'm not mad that I bought the set, but I don't think I'll be looking to add another copy of... More this set to my collection.”

“This is an unusual set but a thoroughly impressive one! The small models remind me of gifts from a CITY Advent Calendar and are of a high individual standard, allowing you to incorporate them into larger displays with ease. The parking attendant's booth is probably my... More favourite part of the set as it is quite unusual and I also appreciate the inclusion of several rare pieces as well as some useful stickers.”
