GM B-body body-on-frame platform — last generation of full-frame full-size GM cars. LT1 5.7L V8 OHV — same engine architecture as the C4 Corvette and Camaro Z28, but with iron heads (vs aluminum on Corvette), 2-bolt mains (vs 4-bolt), and torque-tuned camshaft. 260 hp at 5,000 rpm, 335 lb-ft at 3,200 rpm (1995); revised to 330 lb-ft for OBD-II 1996. 4L60E electronically-controlled four-speed automatic from 1994. RWD only. GM limited the top speed to 108 mph electronically because the standard tires weren't speed-rated for higher. Sedan and Estate wagon body styles. Wagons had simulated woodgrain siding (deletable for credit), Vista Roof glass section, two-way tailgate, optional rear-facing third row for 8-passenger capacity, and could swallow a 4x8 plywood sheet flat. Sedans were 9 inches shorter than the Cadillac Fleetwood. 1996 added automatic climate control standard, OBD-II compliance, and 'Collector's Edition' badging acknowledging the model's discontinuation. Production at GM Arlington, Texas — plant converted to SUV/truck production after 1996. Now firmly cult — Estate wagons appreciating, sedans cheaper but solid.

Strengths

  • LT1 5.7L V8 (Corvette engine) outpunched contemporary BMW M3
  • Body-on-frame construction — robust longevity
  • Wagon swallows 4x8 plywood flat (better than most SUVs)
  • Towing capacity 5,000-7,000 lb
  • Production rarity for final-year (1996) cars
  • Cult collector status now firmly established

Weaknesses

  • 108 mph electronic speed limiter
  • Four-speed automatic dated even in period
  • Heavy curb weight (~4,700 lb)
  • Vacuum-metallized plastic chrome trim degrades with age
  • Rust-prone in salt-belt cars

Notable tech

  • LT1 5.7L OHV V8 (260 hp, 335 lb-ft)
  • 4L60E electronically-controlled 4-speed automatic
  • Body-on-frame B-body architecture
  • Vista Roof on wagons
  • Optional rear-facing third row (wagon)
  • Air-leveling rear shocks (towing package)

Common issues

  • Optispark distributor failures (LT1-specific)
  • Reverse cooling system gasket leaks
  • Vacuum-plated 'chrome' plastic trim degradation (1995-96 sedans)
  • Air shock leaks (when fitted)
  • Rear quarter rust in salt-belt cars

Used-market budget

$15,000

Sedans $8-15k. Estate wagons $14-22k. Low-mile original-condition Estate wagons $20-28k+. Documented Optispark service is critical. Collector's Edition (1996) commands a small premium.
