2. I washed my engine once and the car wouldn't start that night, but it was fine the next day. Personally I think the Opti fiasco is blown out of proportion, although I have the better vented version (95+?)
3. i believe the 0-60 is somewhere around 5 seconds flat (for manuals I believe)

I'm pretty sure the 6spd is faster but that auto is really easy to drive.
Probably the only time I had a problem with the optispark is when I didn't see a 6" stream across the road and hydroplaned about 200 ft of it. Car washes with undercarriage spray and regular wet weather doesn't affect it. You have to seriously try and get it wet to mess it up. I even wash the engine sometimes at the car wash and don't have problems.

2) the opti is a maintenance issue. I have never heard of them "dying" without plenty of warning. codes, bad idle, stumbling, things like that.
3) C&D tested a 1992 6spd, new, and got 0-60 in 5.7. Admittedly, it was a HOT day, about 100*.
4) I have had my vette for 2.5+ years, and 60k+ miles. It has never stranded me or required a tow. In all, quite reliable. Now - it is a bit of a maintenance hog.

Most common cause of opi-spark failure:
- age/mileage (70 - 80K miles)
- water pump leaks coolant onto/into opti
- ignorant lackey at a detail shop pressure-sprays the engine w/ high pressure soap/water or degreasing solution during engine cleanup portion of a complete bumper to bumper detail job.
95 and 96 opti is vented to vacuum to keep moisture related problems minimized.
