Hi,
I have recently purchased a Boxster from Vancouver without seeing it. Got lots of help from a local rennlister there. I would like to pay forward and offer my help. Here are some of the things I could do:
Go to see the car and take high resolution very detailed pictures of every panel. Look for paint blemishes, interior condition and smell, signs of neglect, read maintanance records, etc... Transport the vehicle to a PPI location of your choice and back to the dealer. (CAA will tow there and back for an $70 membership, if needed)
Anything else you need, don't be shy.

Cheers
Stan
