http://www.flickr.com/photos/26861900@N00/As promised, here is the Diner's box. I've never seen this model before. I bought it from a local dealer who bought it 10 years ago. It looks pretty cheesy out of the box but paints well. Be warned though, it only has 3 completed sides, you have to build the fourth yourself!
I also posted pics of my finished a factory, unfortunately it is not perfect in scale, especially around the doors. It is such a nice model to paint I think it looks good.
I'm not sure about Plasticivlle in Europe, although you get buy them online. I paid 40 dollars for all 4 buildings which is a good deal although some of the models were warped or cracked.
In terms of painting I drybrushed everything. I started black and built up the colous in lighter tones. I liked how Grim made the 50's stucco look like brick with red drybrushing. If I found I drybrushed too much or I wanted something to look dirty, I watered paint down heavily and gave the building an 'inkwash' to make it dirty. Those retro posters and ads are the best. The cover all my mistakes.
