So there is an interior difference in 2003? I hadn't gone to look in person yet, cuz I didn't have the money. Now I do, so now I'll go take a look and compare between the '02 & '03. What were the differences?
What is DIC? What's good about it? What's bad?
What's the differences in the hydro boost brakes?
I'll do some googling as well. Thanks guys!
The 2000-2002 interior just looks outdated/cheaper to me. The leather is nicer in the 2003+ models, they have the digital climate control, better head units, steering wheel controls, turn signal mirrors, etc.
The DIC is the Driver Information Center, it has things like AVG MPG, distance to empty, engine oil life, a timer, annual mileage, trip settings (business and personal) that include distance, time, AVG MPG, gallons used, average speed, % of annual mileage. It also remembers your mirror settings, lets your control how long your lights stay on after you turn off the engine or unlock. Little things like that that I hate not having.
The only bad thing about the 2003+ models is the failure of the instrument cluster. Most are going to need it replaced by 100k, many before that, many after that, but odds are you're going to have to replace it at some point. Good thing is- GM has an extended warranty on the clusters and will replace them until the truck is 7 years old and has 70k miles. What usually happens is the MPH hand will go haywire and stick or not register.
Here is how edmunds describes Hydroboost:
"For 2004, Tahoe introduces Hydroboost braking. Most power-brake systems rely on engine vacuum to reduce braking effort, but Hydroboost uses power-steering fluid pressure, which provides added safety, with more reserve power assist for braking under specific conditions. The system will continue to provide sufficient power assist to stop the vehicle even if the engine stalls or is turned off. Hydroboost brakes that provide more reserve stopping power and decreased pedal effort"
The only time I really notice a difference in the brakes in the '03 and '04 models is when towing or when the brakes are slammed on, its not really anything to buy an '04 over an '03 because of, though.
Heres the picture differences between the 02 and 03 interiors.
