Faults:
The battery was severely corroded upon purchase, to the point of leaking blotches of foamy blue copper sulfate. Had to replace the battery as well as the casing, which also corroded.
Tiny oil gasket leak -- minor enough to leave alone.
Slave cylinder needed replacing at 123k.
Front brake rotors warped -- replaced rotors and pads -- 125k.
Front brake rotors warped AGAIN 5000 miles later. Very un-Hondalike. By the way: I drive like an old lady.
Any other repairs were just routine maintenance.
General Comments:
Other than the front brake rotors, my Prelude's run like a top. The engine runs a little coarse when cold, but once warmed up, you would be hard pressed to tell there are 135,000 miles on the odometer.
Amazing refinement and road manners for a Japanese sport coupe. Maneuvering down the highway at speeds above 75 gives you a sense of oneness with the machine I haven't felt since my old 5-series.
Fuel economy ranges from 23 to 29, occasionally 30-32 if you're not in a hurry. Sadly, Honda insists on Premium fuel.
If I had to go back and do it all over again, I would have hunted for one of the 1994-96 models, since those had cup holders. And maybe one of the VTEC models, although the regular Si isn't exactly lacking for power.
P.S. This is probably the best looking Honda ever made. I sometimes catch myself admiring its curvy body in the parking lot.
