Im interested in getting one, but i heard there are many costly repairs involved with BMWs does anyone have information? Thanks

Yes, when you purchase a "BMW" you're going to pay for repairs. We're talking about a Luxurious piece of Machinery here.

ALL BMW's are extremely reliable ... Electronically & Mechanically --if-- you take care of them properly.

The Z series is super fun ... I definitely recommend one; but, and I mean but ... when that rare occasion of needing to fix something comes around ... you're going to pay.
