'95 - Average miles until problems

I really don't know how to explain this well, as for I'm not very good with cars. But I'll try my best, so bare with me.

Ok, I'm looking to buy a '95 Saturn, but I want to know how long it will run well. In other words, how many miles will on average be left when I start to have problems with it.

For example, let's say I have 70,000 miles on it, and it will have a lot of mechanical problems that need to be taken care of.

Anyone have an estimate? If you need me to reword it or something, just tell me.

It really depends on what kind of shape the car is in now. If you can, you should get a mechanic to take a good look at it and see what it needs before u purchase it.

K, thanks for the help.
