You made this comment which brought up some flags in my mind... I have a few quesitons based on this comment. First, have you overhauled your cooling system yet (water pump/thermostat/radiator/hoses/sensor replacement)? You're close to needing to replace your fuel pump as well. This is not hard to do and when you do this (if you do) I would also suggest having your fuel filter replaced as well...
Generally speaking... maintenance on these cars is not hard especially if you have some friends who are more knowledgeable to lend you a hand
If you like this car so much then there's no need to get another
as long as you can properly maintain this car.
When was the last time you had your rear subframes checked out? If you don't know what I'm talking about or if you never have done that I would suggest having your rear subframes checked for cracks...
