Looking to buy 02... a few questions

[bennylava]

Looking to buy an 02 Chevrolet truck. So here's a few questions.

1. I want the extended cab... maybe the 4 door? I'm afraid I'm not sure what the difference is. Was there an extended cab 2 door?

2.Also, I'm not sure if I'm looking for an 02, or an 03. What was the last year of the horizontal headlights? I'm not a huge fan of the slanted eyes look. But I can't remember if the last year of of the headlights I want was 02, or 03.

3. Is there anything in particular that I should watch out for when buying one? Factory defects, commonly known flaws, etc.

4. What were all the colors available? I think I've seen red, white, black, and tan. This would be chevy colors only, as I'm not looking to buy a GMC truck.

5. What was the highest options package? Want to make sure I get that.

6. Was there much of a difference in the engines? All I know is that the 5.3L was available. Did they have the 6.0L back then, or was it something else? And when it comes to modding it a gas mileage, what would be the differences in the engines? I'd like to give it a power bump but I don't want to get 10mpg.

Thanks in advance! I'm sure I'll pop back in here with more questions.
