Why beg for the money to buy a Hummer? If you already have saved $27,000 Dollars, why not buy a used Hummer. I have seen use Hummers for as low as $25,000 Dollars and Up. I found a 2002 Hummer in Arizona on the internet this week for $55,000 Dollars, it was in great shape and never been use off road. There is some great buys out there for used Hummers, you just have to look for them.
Just something to think about.
Good luck
