I got the warranty through the dealer for $3k. I didn't know about '99 block issues, but I still love my '99. I'll check the engine and see if it has been replaced, I have no idea if it has been.
But I have to disagree with Randall on one thing. I prefer the 2.5L. While more HP would be nice, as a daily driver it is nice to have few extra MPG and the lower insurance. I'll concede on the rear window, but since I use a hardtop half the year, it isn't a big deal. Plus, you can always upgrade to a glass window.
