Oh, sorry. If you havent looked at it yet you probably dont know those answers. All I can say is that many pitfalls may lie in a car such as this. They may not be readily apparent either. Often times, without correct maintenance, having a car just sit is worse than driving it. Fluids get acidic and eat away at metal, mice make houses on the engine with bits of wiring insulation, etc, etc.
However, if this car was maintained well, (fresh fluids annually, driven occasionally, etc) it could be a sweet find. How crazy would it be to have a showroom fresh 86' 5.0?
