My wife and I just had our third daughter.(well, she did, I just watched) We are looking at buying a 99 burb with 90,000 miles on it. 4x4 with the 5.7 liter engine. I know its not as cool as the 86 k-5 but the wife likes it. Anyone know of what I need to lookout for in this year truck? Other than the normal things. Any help would be great.
