Want to buy a Mazda Protege 5

My friend is looking to buy a 5 and still looking for one with low miles
Is there anything about this car that she should look out for?
Would appreciate any advise :D

I have a 5 and it has been trouble free. I did remove the roof rack cross members because they made lots of wind noise. I'm pleased with the car and I'm not aware of any problem areas. The experience of other owners may differ from mine.
