Give yourself (and Grandpa) a break... take a peek on Craigslist. You might be able to find a good 4 x 4 that fits your budget nicely, and won't take a big chunk of your Grandpa's war chest.
Heck, with insurance premiums, tags, tax and all of the associated costs involved in buying a new vehicle it's just nuts!
And... don't forget maintenance, especially with an AWD car or crossover.
Bottom line is... pick the best rig for your needs, ego and location.
