i am looking at an 03 and an 05 tahoe. i would like to know if there is anything i need to know about these mechanically and performance wise. is there any known problems with these year models. and what kind the gas mileage do yall get? thank you.

 

Are either of them z71?

 

yes both of them

 

Info from Consumer reports...

 

I'd check out this forum.

They are strictly Z71 Tahoe and Suburbans. I've been a member there for a while but I just sold my 02 Tahoe Z71. I still frequent the site though because everyone is so helpful.

I averaged 14-15 with mixed driving and 17 on the highway. I had a K&N CAI and Corsa Sport Exhaust.

 

i'd say save your $ and get a 07+... it's a whole new truck...

 

Yeah, depending on your budget....the NNBS Hoes are a lot nicer. Improved braking, better sway bars for cornering, and better lights just to name a few differences.
