Hello. I am an avid BMW enthusiast looking to get possibly a z3 or e46 to enjoy on the weekends. I'm not entirely sure where to begin or where to look if someone wouldn't mind guiding me in the right direction.
Welcome first off! And depends your looking for a certain type of e46 or z3 on where to look? Also you looking for a project car or super clean one?
They will both pop up on Bring-A-Trailer, https://bringatrailer.com/auctions/ If you have not been on their site it can be quite addictive. I actually bought my 2008 M3 last March on BAT and was quite happy with the results. Of course you could use the classified section of this site and you would be buying from a fellow member of the club.
