Replying to Should I get a new car

Right now I have a 1995 Nissan Pathfinder SE. It is a pretty nice car and I take care of it pretty good. everything about it is in good condition and works well. but it has 173000 on it. I am not really concerned to much about that because my dad is a mechanic and could fix and maintain it pretty well. What I dont like about the car is that it is under powered it has 150 hp and weighs 4k + so it dogs it going up I-70 plus it gets really bad gas mileage. If I get a new car it needs to be under $10g's and all wheel or frunt wheel drive ~200hp and get around 20street and 25 highway. I was thinking about a 2002 WRX 1995 AuidS6 or somthing around there. My car is worth about 5k what do you think I should do and can you suggest any other cars.
