Can't give you any recommendations for your area, as I'm in the U.K.
I would suggest a Volvo
dealer, but not the one who did the rebuild. Depends if there are any local or not.
You can get numerous problems when mechanical equipment
has been left standing with no use. Hoses, impellers, fuel
systems, electrics you name it will need thorough inspections, drive legs can be a real problem with corrosion
and leaking seals
Personally, I would want a thorough inspection
and extensive testing before purchasing
