2005-2007 Sea Ray DA 320 Options

I'm looking around at all these 320 Sea Rays, but I'm not familiar with what options this boat came with. I'm trying to find some resources that list or give opinions on some that are good to look for when searching for these guys. Are there any accessories or factory options that are nice to haves or must haves?

I see some with bow thrusters, Mercruiser SmartCraft etc...

Primarily looking at the 2005-2007 with 6.2L MPI Horizon v-drives.

Can anyone help me out?

 

Thanks!
