Hi everyone, I've decided to sell my 1994 Jeep Grand Cherokee (5-speed) and buy an ealry 2000's Tahoe or Yukon. I live in Boston, and plan to drive mostly in the city, with occasional off roading (alot of driving on snow). I like the Z71, but also like the more luxurious Denali. Any buying advice, in terms of problems / features to look for? Any good years / bad years to buy? Any MAJOR differences between the Tahoe / Yukon? Any maintenance needed at certain mileage marks? And - do prices come down in the spring / summer when people are not looking for 4x4's in the winter? Thanks!
