Recently purchased used E34

The 93 E34 I purchased runs great and is eveerything I thought it would be, except for this one day two weeks ago when it would not start, after work no less. The car had full power but would not turnover. There was a loud clicking sound whenever the ingition was turned. But no luck. The car started the next day with no problems, and has continued to start everyday. If anyone has experience with such problems help would be appreciated. The car has a manual transmission.

sounds like you might want to replace the starter before it strands you somewhere and dont start at all. Call BMA for a cost.
