1990 Nissan Sunny GSX Coupe Auto problem

[Annie]

I have been endeavouring to keep my lovely old Nissan Sunny Coupe going, but have come up against a major problem in that it needs a new core plug on the engine block, which my mechanic tells me would be 3 hours labour, but the cost of the core plug is minimal.  I was wondering if anyone would be interested in buying it from me, as the chassis is in very good condition, and I really don't want to scrap it as it seems a waste.
