I assume this car is in Vancouver. There is plenty of demand for WB and NB manual coupe 993's in BC. There is a big lack of supply so your friend should have no problem selling it. I bought my 97 C4S in Victoria with 162kms about 2 yrs ago. It was not listed publicly.
A dealer posted a 95 C2, close to the same kms for $68,888 CAD this week. With no accidents his car could easily fetch $85 - 90k CAD. There are a few C4S with 60kms for over $120-150k. Below is a 97 C2S with 110kms for $110k but it has been on the market for months. That is probably your best comparable.

If he wants a quick deal Wessiach (Vancouver) and Silver Arrow (Victoria) would be happy to buy it.
