2000 Olds Alero....will it hold in its old age?

So I have a 2000 Old alero coupe 4 cyl 2.2 engine – anyone have or had one of these cars. So far ive had not one single problem with it and ive had it about 3 years now knock on wood….but it had 84K on it now and im getting worried now that its gettin near its american car life expectancy that it may start to give alot of problems. Any suggestions tips etc.
