I've got the H6 in my sedan and it's been good (only 26,000 so far). You  can only get an automatictransmission with it though. And it has been typically required that you  get the premium options also.Getting the transmission to down shift takes thinking 3-5 seconds ahead.To preserve fuel economy the transmission doesn't like to down shift and  this leads to some frustration. It also requires premium fuel. I've tried  running 89 octane with limited success for city driving it's ok but don't  expect to be able to mash the peddle as the ECU will retard the timing to  prevent knocking and I have had some knock on 89 octane but surprisingly  about the same mpg. Typically I run 93 in mine, since that's what's  available. I get about 21-22 mpg.The timing chain is a 'lifetime' part as long as you keep the oil changed  (all 6.2 quarts of it).The muffler has a spring/pressure activated bypass valve in it.  Theoretically, at highway speeds exhaust pressureis strong enough to push the valve open...

Interesting....I am planning to buy an Outback as well, but I find the difference in pricebetween the 2,5 with comfort pack and the 3.0 quite big. (12.000 euro whichis $ 15,000). You get leather, electric chairs, an automatic with 5 gears(instead of 4 for the 2,5) and 2 cylinders extra. Having read your posting,I think I'll go for the 2,5 with hand gears.Rob
