Default Negative effects of only short trips of low mileage?

I'm looking at a 2001 Impreza 2.5rs with only 28k miles...

it was only driven like 2 miles or so to school and back... I'm guessing the car didn't reach full operating temperatures verry often.

What would be the illefects of a car driven like this ??

the car had its oil changed every 3k, but other than that not much other maintenance done.

IMO since its so LOW it wouldn't really matter at all...

what do you guys think ?

I really want the car... but don't wana buy a Lemon

Exclusive short-trip driving dilutes the oil with fuel and other contaminants (water, combustion byproducts) that don't get a chance to burn off. With this type of use it's very important to do oil changes based on time and not just mileage, if it was run on synthetic one or two changes a year might be ok, more often if on conventional oil.
It may still be ok if they did decent maintenance on it. If you're serious about it and it's in good shape otherwise, have a mechanic or Subaru shop check it out. You can get a pretty good idea of the engine health by having a compression test done and maybe also pulling a valve cover to check for sludge.

if the body and interior are in good shape and the price is right
as long as it runs long enough to find a motor to swap is the only real question

I have heard that short trips are killer for the exhaust pipes since water/condensation collects on the bottom of the pipes and does not get hot burn off as steam. the water eats through the exhaust pipes.

Sounds like you found a keeper! Good luck

awesome, thanks for the great replies guys...

The car is actualy 1400 miles away, so I would have to pay a mechanic to check it out.

I'm wondering how the hell I would go and do that

You couldn't GIVE me a ej251 powered subaru, they should come with flip top heads and extra head gaskets like a snowmobile has a spare belt

drive cycle is the least of concerns, when'd they fix the NA 2.5s... or did they ever?

Definitely needs new spark plugs, they should be all fouled up because they didn't have sufficient time to warm up.

If the car's drivetrain and body are good then go for it. Short trips won't damage the engine unless he redlined it before it warmed up.
