hey guys me and my mate just did sum maths, dug around and stuff, and we found on red book ( hoping its a realiable source) that the power to weight works out to be 118 kw

YES! so legally i can drive it around if i get one.
thats the next point i should get too. Ive been looking around at sum nice 2000, 01, 02 wrx 5 speed manual, and the average price is around 17k to 21k. this again sounds like a noob question, but *rumor* has it that the gear box can be a bit of a problem on a thrashed wrx, and is it a problem i should really look out for? how do i avoid it? and on the stats on those cars i have been lookin at they say that fuel consumption is like 11 lt per 100 km. i know if that u push of ur obviously its gonna drink more. but is that around right?
is there anything else to really look at in specifics when purchasing a wrx?
note : im a subaru noob, none of my friends have then, they have skylines, new golfs, 180sx, 200sx, but none of them have a wrx

i feel like im in the dark.
