Adjustment of Status - I-485

I just received a letter on Friday 26th June that my wife did not meet the amount above the poverty line and they needed new evidence. They could not proceed with my adjustment of status until they get more evidence. She makes $25,500 a year and I notice that the proverty line is around $19,300 for a household of two. It is just get and myself. We just recently brought a new car in the amount of $19,0000. I am going to send that information in as well as price of another asset. I will also include my W2's which I didn't include the first time in the I-864. I make about $25,000. Do you think that is enough for them? After taxes my wife makes abut $16,000. But I make nite though.
