I would have thrown up immediately.
I had a friend who got this car at an unbelievable price. Car ran great but she kept talking about a smell she could not get rid of. Long story short, I sat in it for a few seconds and said I think someone's died in here. ( you could not be in the car without the windows rolled down) She started investigating and yes a man had died in the car....there will be some odor forever.
I still can't get the freaking old banana and apple smell out of my car. I have tried everything and air fresheners make it worse. I gag every time I have to get in there. (My smell is much less today though, thank goodness.)
