I finance cars all the time with no money down. Usually I roll the tax into the loan as well. So you can do it with no problem. At some point in time [usually bonus time] I always put money down and refinance or as someone said expect to be upside down for the life of the loan. A 72 month loan on any vehicle is a bad idea in my opinion, the amount of interest paid is way too high. A lease may be your better option. Find a good credit union if you can they usually have the best rates. Example from my credit union:
