Well, rounding up $75 is one thing...adding another $50k to your income is another!
And I got my car loan with my Dad and neither of us had to prove income (of course my Dad has 40 years of perfect credit and has had a Honda loan before). Heck, they let us leave the dealership with the car without even giving them any money! (We mailed them a check for the down payment later)
Quicksilver $10,000 | Better Balance Rewards $2000 | Sallie Mae $3500 | Freedom $3500
I inflate mine a little bit because I include financial aid in my income, which in all reality I do use for my living expenses, so if verification was needed, I can provide proof without issue.
I did back when I was in college. If you do it, don't be ridiculous and put some amount that is not reasonable. And don't do it just to get a higher limit (which you have no business getting with a lower income anyway).
That said, my amounts were always causally and rationally related. I took into account financial aid loans (which I used to pay my bills), scholarships, job, stocks/CD's, and, of course, money from my parents. 
I did it so that I coud get my foot in the door and get accepted. I knew my limits though and didn't charge more than I knew I could PIF right away. No harm no foul, IMO.
That said, with some CCC's like Discover, you'd be surprised what they will allow you to include as income. For instance, they will allow me to include my full-tuition scholarship at law school as part of my "income." Makes no sense to me since I don't "see" that money, but I've asked two CSR's about this before and both have confirmed. Even with that knowlege, I still didn't include it because then my income would have been something ridiculous, close to six figures with my actual income that I make now.
On second thought, perhaps I should if I want that dang Discover CLI, LOL.
