I have owned 2 GMC safari vans. Both for over 10 years each and 100,000 miles. If they were still made, I'd buy another. Nothing else out there is as comfortable with so much carrying versatility. 5 people and luggage skiing , even a windsurfer inside with the back captains chairs giving a long aisle !! Yes, it sucks gas and doesn't corner but I disagree with the statements about handling in snow and ice , its wide and heavy and I've driven to Tahoe in blizzards and passed Ford explorers in the ditch
Great visibility and comfort is important. Sure they had issues, front idler arms, fuel pump ( change the fuel filter regularly to avoid this) , brakes , spark plugs tricky , radiator, tires wearing unevenly , shocks, radiator sprung a leak, electric window motor (easy to replace yourself)... certainly don't last forever , but the cost of these is nothing compared to what you would pay on a more expensive vehicle. Not perfect, but I think they are a good deal. Whats the alternative ?
