Eh, Levenger has good sales. Now, if you were carrying Louis Vuitton, then SCs have the right to be skeptical about your "need" for a job.
I drive a Mercedes Benz that I inherited from my dad when he passed away. Before that I drove an old Camry, as a grad student should, and was reluctant to accept the gift from my mom. I am driving to all my interviews and fear the selection committee will notice my car and judge me for it. :-/
Personal opinion, don't apologize for it, but if someone notices it or says something, just say its a lovely car and you inherited it from your Dad. I don't know how many people with a MB, BMW, Range Rover, or Jag has said something like "It really was not that expensive" when I noticed or mentioned the car (in a nice way). Like I was judging them. They end up just sounding silly.
