Am I being underpaid? AUS

I sell new cars full-time and currently make $110k a year plus a company car. I work 5 days a week plus Saturdays. I don’t get any commission. I usually deliver around 12–17 cars a month (and occasionally I hit 25+ havent done 30 yet), and the average gross profit per car is around $5k–$6k and 10k on bigger cars, I would say maybe 2 bigger models per month.

Just wondering — does this sound like fair pay?
