I wouldn't even consider starting/driving that car until you have gone through everything thoroughly.
Trailer it home, get it up on jack stands and develop a checklist, go through each and every system in that car. Make sure it is roadworthy BEFORE taking it out.
All it takes is one rusted bolt or one bad brake seal, a fuel line leaking etc. etc..... been there done that, WITH my son in the car, learned a scary lesson.
After all, your son is driving it right? No shortcuts, just not worth it.
If you need more info on how to approach it send me a PM, be glad to help.
