Gen 1: 1996-2001 (UK 1995-2001) CR-V
First of all, I bought it from a dealer with 114k miles, and the car is in prestine condition, so my guess is that it was cared for. I've never felt or heard such a smooth, quiet 4 cyl, especially at idle. It makes my 92 Accord soundlike a diesel, lol.
1) Yes, I am aware of the Honda valve...
