how reliable is this car in High mileage ? I need one. I live in north Miami. I'm planning a vacation to Texas with the family. I need a reliable Suburban. What's your opinion about this ?
Here I will give you a real answer, since some people just like to complain. A well maintained well taken care of suburban with a 5.3 or 6.0 v8 could easily last more than 500,000 miles. If it is the generation with cylinder deactivation you want to get rid of that because it will lower the life of your engine.
