Which used car is better?

Hello,

It will all really depend on the service history and overall condition of each of the vehicles.
Another thing to keep in mind is that given these are used vehicles, chances are you will need repairs down the road, and it might be a good idea to go with a vehicle that will have easier and cost effective to find parts and have service performed.
As we know, the Trailblazer is much more common than a Tribeca. So that could have less expense in services and finding parts.

Also, it all comes down to which one you prefer. It is important not to overlook that aspect as well.

Let me know of any questions.
Thank you
