I'm almost certain its a Limited because of the pin stripe, the fogs in the bumper, and the wheels.

When the GMT800-based SUVs were released in 2000, a 2WD Tahoe Limited was produced for demand purposes. The Tahoe Limited offered several features, along with items borrowed from other GM SUVs. First and foremost, was the Z56 "Police Package" suspension/performance package first shown to the public at the 1996 Detroit Auto Show. Prototypes were made in green and blue, but production was limited to one color only - Black Onyx Metallic. The Limited had no roof rack, but was a standout in that it came factory equipped with a distinctive ground effects body kit, along front and rear fascias. Heavy-duty ABS brakes were borrowed from the Chevrolet Suburban. Bilstein 46mm shocks, front and rear anti-sway bars (borrowed from the Z71 Tahoe 4x4), a 4-speed 4L60E transmission (with transmission cooler), a 3:42 rear gear ratio, limited slip differential and an oil cooler rounded out the performance features standard on the 2000 Tahoe Limited.
The two-tone leather interior, a 120 mph (190 km/h) gauge cluster, an all black grille, Pilot fog lights set in the front bumper and an L31 5.7L Vortec V8 (tweaked to achieve 130+ mph) were among the standard features in the Tahoe Limited. The body sat 2" lower than normally aspired Tahoe's, and the Tahoe Limited is only GM production vehicle to have the special 16"x7" Ronal R36, 5-spoke, aluminum rims wrapped in 255/70R16 tires.
The Chevrolet Tahoe Limited Edition was offered for one year only - the 2000 model year, yet it was based on the first generation model platform. According to research, there were 27,148 produced during this model year, but no known exact numbers for just the limited edition. The original design of the Tahoe Limited was conceived by Jon Moss and badged as the "Tahoe SS" (concept introduced by GM on November 7, 1996). However, it is reported that GM disliked the idea of an "SS" at a time when insurance companies were already demanding higher premiums for SUVs.[2]
A Tahoe Sport was also produced that had a monochromatic paint scheme, distinctive front bumper, but different wheels. It is largely believe to be a Z71 model, but most do not possess the Z71 RPO code found in the glovebox.
