I want to buy my first car, and I found a 23 year old Toyota Corolla with 290,000 km on it.

The price I was given Is very good, and I've been told that it was maintained pretty well, but I heard that after 300 thousand kilometers some important parts begin to break down and I'm scared of expensive repairs.

Could anyone tell me if buying a car like that for my first one is a good idea? Also are expensive repairs likely? I'm not a car guy at all, so I'm a bit lost
