2000 Falling apart?

THis thing is driving me crazy, no pun intended. Four door 2000 Cavy , where do I start. Freakin' noisy strut mounts which sound like they're ready to come through the hood whenever I hit the smallest bumps. Engine light is on I was told it had to do with the O2 somewhere maybe the converter, noisy clanking at start which may be the Cat.Coneverter breaking up and dancing around in there. I want it to have less body roll on the corners, more power and just plain more balls all around. I'm stuck between throwing money into it or trading it for something else. Some suggestions would be welcome on whatever strikes you in the list of C#@P mentioned above.
Thnx

get a nice 2 door z24 if you like the cav. and with it lowered and some exhaust and intake you will have some go........... and corner. nicer tires will help with that also.

^just like every other "joe-blow" ricer... intake and exaust... blah... trade it fro a z24 though, he is right on that.

So keeping it and just fixing it up not a good idea? I was thinking of dropping a Z24 engine into it and doing the necessary mods to make it a stiffer ride etc. I Like the idea of a sleeper, I get a kick out of people underestimating me since I'm a chick as it is, wouldn't mind having a little more to shock em' with when the mood strikes me to go very fast

Sweet Truck BTW

How did you colour the interior? Is it vinyl or painted?
