To get the most from your time here, as you scroll down the page we recommend you do these five steps:
  1. Scan the feedback from ALLDATA DIY users on the right.
  2. Scroll down through the "What's Under the Hood?" section to see a detailed overview of what you get with an ALLDATA DIY GMC online repair manual subscription.
  3. Kick the tires... as you scroll down, make sure you click on some of the little screen shot icons to see some screen shots.
  4. Take it for a spin... check out the live demo and use it to look up your specific problem on the sample vehicle so you know about what you can expect to find for your vehicle.
  5. While you are there, go lookup all the GMC TSBs and Recalls (the list of titles is free to anyone, but the details are inside the manuals).
ALLDATA is the only publisher I know that offers a money back satisfaction guarantee, and check this out: if you ever trade your GMC for a different vehicle during your subscription period you can switch your ALLDATA DIY subscription to the new vehicle for free.

If you have been looking at other products, I promise you will not be disappointed when you see what ALLDATA is offering for less money.

I believe ALLDATA DIY is the best product in its class, but it may not be what you are looking for. So the best I can do is put it all on the table and make sure you have all the information to make an informed decision.

I hope you enjoy visiting our site today, and that you find this information useful. Let us know what you think using the contact link to leave some feedback or ask a question.

Best wishes and good luck,

"After relying on printed manuals in the past, which are more expensive than some people think, I find ALLDATA DIY provided me with all the information I needed for less money."

"I had the suspension fixed within 2 hours after reading the instructions in the ALLDATA manual. Modern electronic systems can make the job look daunting, but not when you have access to the manufacturers' detailed instructions. I am impressed with your system."

There is a live demo of the ALLDATA DIY product that you can preview for free in order to fully explore all of its capabilities and decide if it's right for you before you ever have to pull out your credit card.

ALLDATA DIY maintains two sample vehicle demo subscriptions of their online repair manuals for people who want to get a good feel for what they contain. 

These are the actual full DIY product not just some screen shots like I showed you above. One of these demo vehicles is usually a car, and the other is usually a truck. They change them from time to time to keep it interesting (and if you happen to own one of the sample vehicles, then you just scored free unlimited access until they change it again.. that's gotta be worth a peek, do you feel lucky?).
