Thats people for you unfortunately. I was fortunate enough to have my father pass down his 2000 323ci to me when I got my license. One owner and it's still in the family. I think it's had just about everything but the engine replaced in it but was a blast to learn everything about these cars on. I don't think you will find a cleaner 323 than yours. Good luck with the sale!
