If you want a Tahoe that'll outlive your mortgage, hunt down a 2000-2006 GMT800, the last generation before GM added Active Fuel Management and turned oil consumption into a lifestyle. Those trucks routinely hit 250k miles with just a transmission rebuild somewhere past 150k. Everything from 2007 forward carries the AFM lifter time bomb: one collapsed lifter means a $5,000 engine teardown, and the 6L80/8L90 transmissions fail even when you do everything right. The 2021 redesign rides better and looks sharper, but dealership techs report transmission replacements at 1,400 miles, and GM's killing CarPlay in 2026, locking you into their buggy infotainment forever. Buy a GMT800 if you want peace of mind, or budget for an AFM delete the day you sign. Skip this if you want a full-size SUV that doesn't require a maintenance prayer circle.
The R1S is the electric SUV that actually goes off-road, with supercar acceleration and 410-mile range wrapped in a thoughtful three-row package, until you hit the systematic wind noise, suspension rattles, and software bugs that plague both generations. Gen 2's emergency door release requires removing interior trim panels to escape, a design choice that borders on reckless in a family vehicle. If you're willing to beta-test a startup's learning curve at $78k-$127k and can live with inconsistent service access, the capability is genuinely special; most buyers will find more polish and peace of mind in a Model X or established luxury brand.
