Impossible to tell. White paint hides a lot of sin. It might be ok, but the trunk lid rust is inconsistent with the rest of the car. Besides, it’s only a slant with a worn out suspension and the interior only looks good in photos. Note the browned out piping on the seats. That interior is crispy. For $15k...there just isn’t anything special about it to justify that price. Sure, you can modify it but there are a lot better ones out there to do that with for a lot less.
