I would definitely not take the risk. A few years ago when I still smoked cigs I took a non-smoking co-workers company car for the week he was on vacation. I only smoked a few times in the car during the week and made sure I did not at all for the last few days. Then a got the interior detailed. When he got it back he immediately said WTF you smoked in my car? I would think that cigar smoke would be far worse to cover up.
