Check out my new car!

Literal

I [of-の] new car [object-を] look [imperative-よ].

見ろ is the rough/direct imperative form of 見る — the bare imperative is masculine, confident, slightly rough. Combined with the emphatic よ, this becomes a proud, excited showing-off command. Typical casual male speech among friends or family. 新車 ('new car') is a compact compound.
