W140 S320 good or bad?

Hello my dad wants a S320 w140 next year. He is fascinated by this car. I love bmw myself but the W140 is simply an incredible car. He looks very safe. My dad is enough the driving performance of the S320. only what should we pay attention to at the 320er? bj 1997 best with a maximum of 125,000km. claps or crunches the car? is because damn important. for him and me. as I said also afraid of envy. it would be a pity if the car is scratched. i bi n only 22 but I find this car simply beautiful. best the smallest rims so that the car is nice standard For my dad especially feather comfort counts because of rides on bad roads to Poland etc. and he should not be so broken. except brake and small parts should the car not miss anything or? what had you already had for repairs? thank you already for everything. I myself had a bmw 540i e39 and the race was great. glided beautiful feathers quite well just beautiful. ic h hope the S can do that even better.
