O oh. I hate to say that but you paid double for the car that aint worth half of it.
I really hope the car was maintained, I just dont want you to realise that you need to replace all your bushes, control arms, all struts a complete new cooling system , ccv and clutch within the next 2-3 months.
Best of luck with it.
Care to post some pics. I used to have a 99 323i, who knows , it could be my very old car ....
