Engine:
J: bullet proof and willingQ: very reliable and very powerful
Handling:
J: 93 J30t had the HICAS system. My 95 Jt (no HICAS) handles superblyQ: great from what I hear
Brakes:
J: fantasticQ: undersized
Maintenance and Cost of Operation:
J: cheaper than the Q but not cheap Q: more expensive than the J
Transmission:
J: can be a weak point without proper maintenance.Q: not too many problems.
Fit and Finish:
J & Q: about as good as it gets.
Notes: J is a personal luxury car. Q is a luxury car.
Opinion: If I knew now what I didn't know when I stumbled across the J, I would buy the Q. However, such a low mileage J30t with the HICAS system and it's beautiful unsullied paint job would be very hard to walk away from.
Recommendation:
Buy the J and the Q.
