Wow I'm impressed!
I havent had any major replacements done and I've owned the car for 9 years. I dont beat it either. I did replace the heater core, water pump and head gaskets at one point or another. Other things just were just minor repairs. I'm kinda freaked out.. like waiting for something to go wrong.
My oil pressure gauge (stock) I dont think works very well. Sometimes it sits on the red line all day long. I've noticed this for years now. It occasionally rises up every once in a while. It makes me nervous because I think well what if my oil pump is about to go out someday, I will never know. My fuel guage is f*cked too.. sometimes when the tank is close to low it will rise all the way to the top
I suppose I could put some after market guages in but I dont know the first thing about it.
