I would suggest the following:
- Have one of the moderators move your thread to the Diesel Discussion.
- Update your profile to include your location.
- Ask if anyone lives near and would do you favor of putting 2 eyes on it and checking for rust, rust, blowby, and rust.
- Then if it warrants a Prepurchase Inspection, ask around for names of shops that are near the car that could perform such. Recognize that the dealer selling the car may or may not want to accomodate such a request.
Good Luck!
