Prioritize DA over keywords in expired domain?

I'm working on a new niche site and have found a couple of expired domains.

Say my niche is sport cars. I have two domains I'm considering to use for my site:

AwesomeCars.com - DA 18

Or

Sports-Cars.com - DA 3

What would you consider more valuable? I'm obviously going to work on the site plenty over the next 12 months or so, but getting a nice big boost right off the bat with a DA 18 seems quite nice, especially since it still relates to my niche.

But since I'm targeting a sub-niche specifically in sports cars, do you think that should take precedence over the high DA?

Ignore DA - check the the backlinks if there is something really good, if not - just pick the better name.
