1. [An excess, plenitude, a surfeit] of the sun is harmful for your skin. [Sounds fine to me. I'm not familiar with "plenitude", but from the dictionary, it seems ok. "An excess" would certainly be the most common term.]
2. [An excess, plenitude, a surfeit] of cars in our city is detrimental to its citizens. [Also sounds ok.] (May a noun in plural form appear after an only-singular noun?) [Yes.]
3. May a noun in plural form appear after an only-singular noun? [Ok.]
