Welcome to Bimmerfest!
You will be looking for a late E36 (3 Series) an early E46 (3 Series), or a mid production E39 (5 Series). To be completely honest, buying a nearly 20 year old BMW with 150-200k miles, it IS going to be a money pit unless come across one that has been exceptionally well cared for, with all maintenance records and everything up to date. The price for that unicorn will probably be commensurate with the condition. The old but true adage, you get what you pay for. Good luck with your search!
