Art Silva Toyota, Sioux City, IA?

I just put a deposit down on a Tideland #4 with this dealership and am wondering if anyone has any experience with them? My receipt is coming in the mail (I live 2-1/2 hours away) and they told me they have 7 cars coming in at the end of August/beg. of September b/c they just built a new dealership (Toyota allocated the cars b/c of that).

I got burned 2 years ago with an OKC dealer and am a bit nervous because of that...
