I'll be honest.. mine smelled old when I got it and I loved it.
My wife always hated the smell of the interior.
After two years of ownership I had someone in our club re-tack the headliner the correct way. In doing so she found two dead mice up above the headliner/rear side panels. That was the source of my "Old car smell".
Now I keep Bounce dryer sheets under the seats and the interior always smells nice
