Do you need a spare city to buy a fourth-level improvement?
Several experienced players agree on this; there is no official ruling.

Yes, in effect. To buy a fourth or fifth level in a colour you need a city that does not already carry a metropolis, since that is where the metropolis would go. Players debate how strictly this applies when your only city carries one.
