facebook advertising question

I have a question regarding facebook for advertising in my niche. I am selling physical products with an average order range of $30 to $200 per order and the products are in the motorsports/automotive niche.

So, we have:

1. Physical product, shipped to customers door.
2. An ad clicking user has to go through my website, and then exit to the vendors site to make a purchase. I cannot sell them the product on my own page, they must continue on to the vendors page. I can also not direct link them to the vendors page from Facebook. They must come through my site.

My business is nice in that one new customer could become a customer for life that buys thousands of dollars of product over a ten year span, but I am looking for this to be immediately profitable, meaning if I spent $50 on advertising, I profited $100 on sales.

Is this:

1. Certainly something that with the right demographic targeting could work on Facebook.
2. Given the information, not something that is likely to be profitable on Facebook.

I have yet to find any real success on Facebook for this niche so I am trying to figure out if there are certain things/conditions that just aren't good on Facebook or if it truly is just a matter of super tight targeting.
