Compact enough to find parking in a busy city, but large enough to haul what you need.

I like that I have the option to lay down the back seat and have a full size bed, but still compact enough to park in a busy city. The ride is very smooth and comfortable. Large enough for the whole family, but still gets good gas mileage.

Good on gas considering it is a beast.

I love my truck, drives great, went to Huntsville Alabama 70$ -100 mph drove like a dream, sits up so you can look down on others, turns on a dime, I call it the beast, the radio is awesome, big enough back seat for me to sleep comfortably, I love the get up and go it has, and my son loves it too.

Kenneth J

It is dependable as well as versatile. It is also a comfortable vehicle to drive.

I like the versatility of my vehicle, and it is dependability. Also it has required mostly, basic wear and tear maintenance. There's not much about it that I do not like. However there's been a few issues that are costly repairs.

Power durability long lasting power has many stamina

Oil consumption is very prominent. The car is very heavy. Turning is not as agile as other cars. It needs to put air conditioning all the time because it gets hot way to often. It carries a large load. It is very specious it can fit all types of things in there no problem. The windows are thick

Terri J

I take care of my truck and I love it. It helps me with my hobby.

My truck is roomy. My truck is versatile. My truck gets poor gas mileage. My truck has over 200K miles on it. My truck is dependable.

Crystal B

I can extend the bed into the cab of the truck.

It's used and was when I bought it, so it has its little problems. The speakers need replacing, I've replaced 2 of the door handles and a transmission. However, if the previous owners took better care of it, I believe there would be none of these problems. It runs and drives great.

Tamara S

Comfortable seats and reliability

It hasn't had anything major happened to it. Transmission had been replaced. Regular oil changes have been performed. It is a very reliable vehicle, the most reliable one I've had. It has 4 wheel drive, anti lock brakes, power windows and power steering.

Cristina P

Best truck I have ever bought and reliable since day one.

I have an 03 avalanche that I drive daily. I love it,I've owned it for 9 years. The only problem I have had with it is my air conditioner had a leak. I got it fixed now it works excellent. It does have a small bed but with the back window able to come out completely it makes it a longer bed. The inside is very spacious,I've had 6 people in the truck and they still could move around freely. It has a moon roof that's nice if I don't want the side windows down. I have taken the truck on many trips and always got to point a and b safely. I also have loud pipes on it which my son loves:). I would definitely buy another one any day.

2003 avalanche is a reliable car to own.

It is a very reliable vehicle. We have had it for sixteen years and it is still running. It is also a very safe car to drive. It has survived accidents and inclement weather. It is great in the snow and the rain. The seats are very comfortable and it is a very smooth ride. It is also super roomy and has space for five adults.

Elizabeth T

It is relatively good on gas.

It is getting old, and is starting to break down. The starter has major problems and it is a gas guzzler. It is not going to last much longer.

Stack H

Truck that's not for sale

Needs computer and new battery..but other than that the vehicle is a champ when driving was available.I love the color and the trim and off road package. Tiny windows and backup up camera with a stereo system already included in the vehicle. Overall I love the truck

Heather F

It is a spacious vehicle, but it is always having mechanical problems.

It is not the best vehicle I have ever owned. It seems like every time I turn around, something else has to be fixed on it. I am constantly sinking money into this truck for repairs.

Ryan A

Chevrolet avalanche is a great family truck.

The Avalanche is a great vehicle for people that want the ability to haul goods while still having the convenience to haul family and friends. It is highly reliable and drives very well. It is a little expensive to work on when it needs work. I would recommend it to a family that needs both the space for people and a truck.

Tamara J

2003 Chevrolet avalanche great for hauling and towing things.

It is a very good truck for hauling and towing things, it is very powerful, it is comfortable but it takes a lot of gas, my husband tows a utility trailer and a 21 ft travel trailer with it and also hauls things in the bed of the pickup, it is more of a work truck than a passenger vehicle though.

Sheila C

My green machine: has room and power, and functionality.

I love that it is a truck, but the gas mileage stinks. It is a 2003 Chevrolet avalanche. It is my first truck. The performance is good, but I wish the Chevrolet brand had a better gas mileage. It is a reliable truck and will never get rid of it. The avalanche has a corvette engine, which is cool. I guest I rather be in truck than a small, low to the ground vehicle.

Josh M

The space of the truck and the interior inside is nice and comfortable

It's a okay truck it has a lot of space and has a decent speed to it.

The most important thing about my vehicle that others should know is that with this vehicle you get the best of both SUVs and trucks.

I love my truck. The sound system is good. I can haul anything when needed. It has a comfortable ride. Only dislike is that it is getting older, so repairs are becoming more costly.

Beckie S on March 8, 2021

Chevy Avalanche: good looking and versatile

I think the seats are very comfortable. There are lots of adjustments so it can fit any size person from short to tall. I love the versatility in the bed size where you can have the 6 foot bed or you can make it longer by removing that lids and putting the back seat down. I do not like that it rusts on the back quarter panel over the tires every avalanche I've seen rusts in the exact same place and it rusts a lot. It's been very reliable for me as a four wheel drive. I've never gotten stuck. For a 1500, it's got pretty good towing capabilities.

Is The 2003 Chevrolet Avalanche A Good Car?

Yes, I think so. Because I've drove my truck pretty rough and it's held up very well. The motor has been good and the wear-in-tear is also pretty good.

Stephen M.

I definitely say that the avalanche is a excellent vehicle. I've owned mine for over 6 years and have not had any major issues. I love how spacious it is.

Very reliable. Only problem I had was a/c had a small leak. Had it taken care of right away. Always starts when needed gets me through any kind of weather and road conditions.

Lisa T.

Is The 2003 Chevrolet Avalanche A Good Value?

I paid $7,000. Anything under $10,000 and over $3,000. I would say is good value. In my opinion. And for where I live.

Mat B.

I paid 10,000 for my truck. It's worth a lot more than that since I have done body and interior work to my satisfaction.
