回複：Help!!!! 買車時,被trick $3,000.

TX laws has regulation on dealer, you need look into those. Do your own research rather than ask strangers.

As contract itself, there will be no way back when you sign it. (there are 3 days remorse in some states, not in Nevada.)

Next time read before you sign.

P.S. : 30% of what? Sales Price, $3000, or your net worth? You need learn how to be detail oriented starting now.
