what car had the most cigarette lighters? Did any car come with more than 8? Or ashtrays? Did any car have more than 5?

a 68 Lincoln Continental had 7 lighters

A 66 Lincoln had 5 ashtrays

of course, I'm not going to spend the time to verify these, I'll just go with the testimony of https://www.facebook.com/groups/1649370045277547/permalink/1954942208053661/

a sign of the times, cars now have 6 cup holders and no ashtrays
