Hey Everyone, New, and looking for your advice and opinions.

Hey everyone. Hows it going... I'm new to the forum and what brought me here is I might be getting a 99 trailblazer.

About it.. It is fully loaded.. i mean eveything from power options to heated seats and mirrors, 2 tone leather interior.. you name it.... and at the same time, its MINT!!!! no rust, no damage, 2 owners.. AWD. 4.3 Vortec motor.
It has just over 200 thousand kms on it...

Now, i did some asking around, and I was told to stay away from it, that it will give me nothing but problems and cost a lot in maintenance.. So now i'm bummed.. Cause i liked it.. But a mechanic said is not a honda or any kind of import and last up to 300-400k...

So I would love to hear the up most honest opinions and suggestions about the trailblazer... Hows yours working, whats your kms, approx how long of a life span does it have. what are some things i should know about the trailblazer ie common problems, and most importantly, how is the gas milage on it. And for the younger guys out there, approx what are insurance rates??
Be honest, this is truely helping me out on my decision to if I want it or not... I figured I would come right to the source for help!!!

Thanks very much...
Brian
