The 1990 Celica GT-S is fairly fun to drive. The instruments and dashboard were nicely designed as it makes you feel very comfortable being in. The only downside to the car is the fact that the US DOT, instead of giving the GTS the power it should have had for a sports car, gave it only 130 HP using the same engine as the Camry. Unlike in Japan and other countries the GTS also known as the GT-I(R) had 160HP. Other than that everything else of the car is fine. On another note if you are looking to increase power out of the 5SFE engine in the GTS you wont find any parts for the GTS, although the GT does use the 5SFE as well the GT and CAMRY has more parts than the GTS.
My favorite feature of the car is the EXTERIOR design and Interior design. Toyota did an excellent job of designing both the inside and outside of the car as it keeps making you look at the car and say "wow nice car!"
As I stated earlier we all expect more power out of a sport car. With only 130HP and 140LBS of Torque the car can't even compete with 1990 Nissan 240SX 140HP 152LBS Torque with about the same power band. As I said earlier a sports car desevers more POWER.
