There is no way neat nick GA would purchase a 2 yo car with a huge stain in the trunk. Stain removal techniques now a days are advanced, I don't believe the dealership would put it on the lot like that, they would remove the stain or replace the trunk liner.
Exactly also taking in consideration his families long history in the used car business. To me this would be a big turn off when purchasing a 2 year old car.
