Have you ever seen any Japanese car with more than 200k miles?
High millers I have seen are upto 130-150k top.
What happens next?
Do they disintegrate and transform to carbon and ferrite?
The point is that I'm looking to buy Subaru Outback 3.0 RN for forthcoming winter runabouts and am bit worried if this is good idea.
Has anyone got any experience with Outbacks?
I had Subarus for 17 years and know a fair bit about them. You're right in that not many get past 150K, but I would hazard a guess this is more economically governed than anything in that it become unviable economically to keep the car on the road as the values plummet when they get real leggy. Also there is a huge breaking scene for Subarus especially Imprezas where you often see perfectly roadworthy cars broken as they are worth more in bits due to some of Subaru's parts prices being a bit mental frankly!
What I can tell you for definite is the following:
Stay away from any Subaru diesel engine, they have a lot of problems some requiring a full bottom end rebuild which is expensive.
The 2.5 petrol is also a flawed design, it's OK in cooking spec (although you can still get head gasket failures), but in tuned spec (STIs) it is a ticking timebomb and usually has ringland failure on cylinders 3 and 4. This requires a full forged rebuild to properly fix as Subaru really messed up on this one. Budget £3K minimum for a rebuild.
Some of the earlier Impreza shells (1993 - 2000 and 2001 -2003 models or classic and bugeye as they are have a water trap around the suspension turret on the rear arches and the first you know of this is a slight bubbling on the exterior of the rear arch.... start clearing that away and you find mega trouble.
That is all fairly moot though as you are looking at an Outback 3.0 RN which is based on the Legacy shell and has a 3.0L boxer engine.
The 3.0L is a great engine and as long as you rigorously adhere to oil and filter changes will give you years and years of trouble free motoring. The Legacy bodyshell also suffers from no known major corrosion issues so that is a bonus, but I would still keep and eye on all the wheel arches. Outbacks by their nature tend to be taken places where other cars aren't so keep an eye on the paint and underbody protection.
The clutch pedal on a manual may feel a bit weird when you test drive it, the bite point always seems a bit higher than it should be, but that is just the way they are.
One other thing to look out for is on the back of the car where the exhaust splits in to two there is a Y pipe and it has a habit of corroding through.... it can only be purchased from Subaru and costs £500. One guy I know has a full custom exhaust made for his car for about the same rice as that one part LOL!
Other than that the Legacy is a very nice place to be, a far better car than many give it credit for and not as brash or common as an Impreza. Get the best you can and intend to keep it for a while and you won't go wrong.
The UK Legacy forum is worth joining too, a very sensible decent bunch in there.
