Welcome to the Q&A Forum

https://www.youtube.com/watch?v=mQZY7EmjbMA - Here is a video on how duplicate content is handled by Google. Here are my thoughts, it would be better for you because the searcher who types in the specific make and model in your inventory will be able to find it quickly, as opposed to having to click through a site. Theoretically, that is the benefit. It could also be that pages don't rank because all of the content is viewed as duplicate. I would make the decision based on what is best for the searcher, which would be to have an organic SERP with exactly what they are looking for.

There are plenty of photos on the Google+ Business page.  I appreciate the quick response and you confirmed my own thoughts.  The odd thing is that sometimes a photo shows up, and sometimes it doesn't, depending on slight variations in the branded search term.  I think it is as good as we are going to be able to get ti at this point.  Thanks again!

Personally, I would stay away from Cloudflare (dont hate me LOL) W3 Cache is good. I love WP Rocket though. MaxCDN (find a coupon for a discount) Then any host that you can find that passes your standard. This one is subjective. People think mediatemple is really fast, I've experienced both sides of the coin. Inmotion, heck even hostgator is good. The only advice i could give is to try and test them. Rackspace has been great for me if you like a cloud host but I find digital ocean to be acceptable for me as well as Im not going for ultra fast.
