I got my 240 as a 16th birthday present in '97 and have been driving it ever since. I absolutely love this car! The manual transmission is so much fun to drive, whether it's up and down hills, in the city, or on the highway. I don't know if this is just my 240, but it's never happier than when it's doing 90+ on the highway. A bigger back seat would be a dream, but it's a 2 door coupe, so c'est la vie. I actually feel like it has good-sized trunk for a car of its size. Have had no huge problems in all the time that I've been driving it, other than a recently undiagnosed problem with the car starting from time to time. Drives smooth, great brakes. Would recommend to anyone who enjoys driving.
The smooth transitions between its five speeds. Easy to change oil and oil filter. Smooth external body contour. Easy to use, intuitive layout. Well placed speakers.
Like a couple of others have said, a cup holder would be great.
