Thanks guys!

How many models will this set contain?

The quick answer is : A lot!
Already modeled and ready to go are:

The Book Store
The Church
The Road Pack (roads, city squares, road signs, traffic lights, street lighting, power lines etc...)
Nature pack 1 (treees, bushes, flowers...)
Nature pack 2 (park, hedges, benches, kiosks etc...)

That's just the beginning. In the works are Rows of Buildings (most likely easy-posed, so you can make your busy street as curvy as you want)
The City hall, the Gendarmerie, the School, the Cemetary, the River are all either in the works or in the plans.

In the plans as well (but I haven't started work on this yet), will be a pack of low-poly people and cars, so you can really fill up your scenes with life without killing your machine.
Since the village is pretty much outside of time, I'll make both people and cars from various eras (around WWII, in the 60-70's, today)

As for making another car... There are quite a few excellent models out there already, I don't know if it's really necessary to add more, unless it's very different from what already exists.

Anyway, that's what's in the plans...

Thanks again for your great support!
