I bought set 4942 yesterday at Target. I have been trying to buy it for almost 3 years. I finally bought it. When I lived in NC they didn't have it at Walmart or Target. When we moved to Florida they didn't have it. When I came to visit my Grandma in NC they had one, only one. So im happy! Its going to be some sort of Brush/Utiity/Car thing when I get home.
Overall its a pretty good set. It looks like any LEGO city set. It has all blue lights and a "LEGO Set" type of skid unit/Pump trailer. Its not that realistic. I'll give it a 4 out of 5
Glad you bought it! Another place to look for older City sets like that is Books-a-Million. They have about 8 or 10 Lego sets at a time in their kids section. No one ever knows to look there, so there are always old ones.
