“Even the current 80-series Supra is over five years old, so the earlier 70-series gives you a wide choice. We mainly stock tuned 3.0- and 2.5-liter cars after the 1988 facelift. Prices have become reasonable, so many younger buyers come in. Some are tired of Hachiroku or Roadster and want more power; older buyers sometimes buy one for nostalgia. The 3.0-liter M-series was once avoided, but it is now popular alongside the 1JZ. The 80-series is heavy, so even a tuned twin-turbo 2.0-liter 1G (GA70) cannot be expected to perform well. If buying now, the naturally aspirated version may be cheaper and a better choice.” —Wakayama, King Buyer. “By the way, the Turbo A introduced in 1988 was limited to 500 units, so prices remain high. Many are in excellent condition, so it is worth searching patiently.”
