A similar sized vehicle to the Cruiser are Tahoe/Yukons and Expeditions if a good Cruiser can't be found.
GMT800 or 1st generation Expedition. Both durable with engines that regularly exceed 200,000 miles. My 2000 Suburban is at 270,000 miles. New York taxis and limousines ran those 4.6 and 5.4 Ford modular engines 300,000 miles.
They are reliable and last with proper maintenance.
The northeast is the perfect market to sell the Saab, west of the Mississippi, not so much.
Hope you don't have to rush to buy a vehicle. Do your homework and don't rush in to buying a troublesome vehicle.
