Forgot to add - I would also need to see if the seller is open to a PPI. I've never bought such a high $$$ car privately that is this old (always much newer with either factory or aftermarket warranty, or a much cheaper car) so I think a PPI is a must.
If anyone has any recommendations for a good place to get an E92 PPI in MD I'd greatly appreciate it. I've noted a couple of shops and would love to hear any feedback on these:
