I bought my 03 Trailblazer used for $2,200 about 6 years ago. I have been in love with this truck ever since. Other than it being difficult to fuel, there is obviously a issue in the fuel inlet line (that I have never had checked but recently bought a 6ft. long inspection camera with LED lights on the tip to check into it) I haven't had to do anything buy but tires, a battery and change the oil in the first 5 years. I have had to put a significant amount of money into it in the last year, but only after my daughter took it off roading several times work her idiot friends that don't know a 4×4 from a passanger vehicle. So I did but front hubs, upper and lower ball joints on both sides, inner and outer tie rods on both sides, front lower control arm mounting brackets on both sides, both tail light assemblies, transmission safety interlock switch, brake light switch, cam shaft positioning sensor, Cam shaft actuator, alternator and starter. I have been chasing electrical issues and replaced the cigarette lighter and auxillary power port in the dash to resolve the OBDII port not having power. And am currently working on the brake lights not working. I know this sounds like a lot, and if you can't work on it yourself and have to pay a mechanic I'm sure it is. But all this was after 5 years of turn key driving. As well as after letting my 18 year old daughter drive it unchecked for over a month. And my wife drive it the first 5 years and absolutely refused to do any kind of maintenance on it to prevent future issues and catch the little ones before they became big ones. So if she had treated it properly and my daughter has kept the wheels on the pavement the vast majority of the work I have had to do would have never been a problem. All in all this is a strong engine in a very well designed 5 passanger midsized SUV that has 250,000 miles on it and the engine has not missed a beat. The standard issues with parts failing when they are not cared for or simply get old is about all the issues you can expect. And if you're doing it yourself working on this truck is easy. Just do yourself a favor and get a good heavy impact wrench, DeWalt has a good one with 700ft lb of torque. It will help with any suspension parts and taking off tires. Or you can get a 1/2" torque wrench and breaker bar and your set. My experience with this truck has been great. I wouldn't sell this truck for any amount of money even work the work I'm doing to it. It's a great vehicle that has been mistreated by people who don't know better and won't listen so they can learn. Remove them from the equation and this vehicle is an owner wet dream!

Easy to drive, easy to maintain. Entering an on ramp at 40mph, if you step the accelerator to the floor mine goes from 40 to 90 plus mph in 2 and a half seconds. 4.2 vortex v6. Scary fast. Mine is 4wd, currently won't engage will repair and pass truck to my daughter

Bought this 2003 in July 2018 for $600. Did some basic maintenance (fuel pump, coils, brakes, u-joint) and have been driving it with no issues. In early June of this year, I took it on an 1,100 mile trip from NH to SC. No problems and the 4.2 averaged 19-21 MPG.
