the IS300 was a GREAT car. Bulletproof motor, subdued good looks, fun to drive, easy to mod if you're into it, lasts just about forever, gets decent mileage for its size and performance, pushes the right wheels... the 2JZ is an amazing motor and the car is very comfortable. I miss mine.
Really good cars they will do at least 140, my dad drove with his friend up to northern california and they did 140 on the way up there in it, theyv got a awesome instrument cluster in them too, awesome car in general, there actually not that expensive, cause everyone wants the is250 or is300 cause the new body but the old one is still a great car and i doubt there still really expensive
