The Structure of Arguments

The first paragraph of the exercises is an argument.
My neighbor should be forced to get rid of all the cars in his yard (1). People do not like living next door to such a mess (2). He never drives any of them (3). They look old and beat up(4) and leak oil all over the place(5). It is bad for the neighborhood(6), and it will decrease property values(7).
There enough premises and additional ones are not needed to make the argument stronger. I think that this is a good argument because there are several premises that seem to be valid. Also since this is coming from a neighbor which makes the argument stronger. The person giving the argument obviously lives close to the neighbor and witnesses this every day. The argument could be better if there were more evidence from other neighbors or at least their support since this affecting the whole neighborhood.
