I've had my '95 SC300 5 speed for 15 years now. (It'll be 16 years this July) Just can't find a reason to replace it. Still Love it.
Other than the normal maintenance, a starter motor, Oxy sensor, Clutch, Trunk Opener Shocks and a Radio Antenna, I haven't had to put any money into this work of art.
My 16yr old wants it now, but I'm afraid something might happen to it.
Out of the 15+ cars I've had in the last 42 years of driving, this is by far the best car I've ever owned. 20 MPG "Average" to boot.
BTW, the 5 speed models only account for 5% of all SC300's. A nice rarity if you can find one.
The SC400 is a real power house, but having a stick is a lot more fun in my opinion. Both cars are expertly built.
Good Luck...
