Sorry, maybe "nothing" is a bit harsh, also I don't know your local market, so maybe it will sell. Maybe you will be able to position it for the phrase "gold/silver loans" and make affiliate commissions, I wouldn't know, I don't dabble in SEO. I actually have a very similarly constructed domain creditdebitcard.com and I sure hope it's not worth nothing.
Most importantly, take anyone's opinion with a grain of salt, especially on the Internet.
However I think we can all agree that CheapUsedCars.com and your or my above-mentioned 3-word domains are absolutely in another league.
