GarageScout Take

One of the first 30 1963.5 Avantis built to start the 1964 production run, according to the Avanti Owners Association International. Its Jet Thrust 289ci V8 has an R2-style Paxton supercharger, and an engine-out refresh and reseal was completed in August 2025. The 200-4R automatic was later rebuilt that year with a replacement torque converter.

Strengths

  • Early 1963.5 production status
  • Paxton-supercharged Jet Thrust 289ci V8
  • Documented 2025 engine and transmission work
  • Custom black-over-tan presentation

Watch For

  • Total mileage is unknown
  • Trunk seals need replacement; a replacement set is included
  • Fuel gauge is inaccurate
  • Voltage drops under heavy electrical loads, and the transmission previously showed second-gear slip before its later rebuild
