How much does a master cylinder oil leak, and door lock issues cost on a 95 993?

[pyite20v]

Im looking at 95 993, and the owner stated that he knows there are some issues with oil leaks, the master cylinder, and the door locks. How much can these issues end up costing? What of them can I fix on my own?

Thanks for any advice. I know I should get a PPI before I buy it, but I am going to try to talk him down tonight, and wanted to know what these can end up running.

Take it to a reputable mechanic!!!! He will be able to advise you on the overall condition and approximate repair costs! Avoid the dealerships! Where are you located? Lots of knowledgeable people on this board!!
