dont worry john, i was like you when i first got on this site, i hadnt a clue what i was doing.
as for that car, in my opinion it looks like it has got paint at some stage, some of the badges are not right, its missing the pink sti badge on the grill and front wings, the fog light badges are not orginal either and also the side and rear badge dont look right, there not the ones that come on the car. the front lights are also off a later model, i cant work out if its a v3/v4(different dash) from the pictures. a car with that many miles and unmapped in my opinion wont last much longer i.e. the bottom end will go and would would be looking at a rebuild at a cost of around 3k.
now infairness its a cheap car for the price but dont except to buy it and drive it without no problems for the next year or two.
get someone that knows subarus to look at it for you to see is it a straight car but even they wont be able to tell you if the bottom end is on the way out
