I test drove both vehicles. Tahoe is roomy, has plush seats, and a great vehicle. Only drawback is that it is a gas hog. I really liked the Endeavor. It rides like a car, gets better gas mileage than the Tahoe (although it only takes premium fuel). I am a 29 year old single male. I like the size and comfort of the Tahoe, but gas is over $3.00 a gallon now. I like the Mitsubishi, but I don't know much about the cars. Please advise!
