I'll go against the grain here. I would see what it cost to fix the leak. Those Yota's run forever if you "some what maintain them". My daily driver is a 96' Avalon with similar package (leather, sunroof, 3.0 V6). I love this car, bought it from my parents a few years ago, who bought it new in 96'. I'm close to 190,000 miles, car still runs great and gets me close to 30 mpg.

All I do is change the oil on this thing. I have dumped about a grand in it to fix things that are broken, but that's it.
