pdq, anyone who has a paid-for vehicle that is healthy should forget about a new vehicle that may be cheaper to run. Wait till 'old faithful' actually needs last rites or the repairs are substantial before thinking about a new vehicle.
That Suburban is a real hauler; here in Alberta they are fitted out and used by the Hutterites to take the women to town for shopping- hence they are called 'Hutterite taxis.'

A neighbor just bought a Tundra with all the extras, but he is replacing an old Chevy pick-up with many old vehicle diseases.
The Tundra is well-put together, but use your old vehicle as long as she still perks.

I am some envious of my younger son, he just bought a Lexus SC in almost new condition from an airlines pilot with old maid syndrome- a beautiful little car with a helluva price tag ($70,000 new?) that cruises easily at autobahn speeds- rated 16mpg city, 23mpg highway, $3400 for 15,000 miles, according to the government figures. But he has an SUV for work, and his wife has her own car for her job.
