New Job at Dealership

Just started a new job as Parts Back/Front counter at a Dealership in North Florida and wanted some opinions on my pay plan.

Was a detailer for most of my working career at various dealerships, so yes I am a rookie but I consider myself to be a quick learner.

My pay plan is 500/week paid bi-weekly, 1% commission on total parts department GP, and 2% commission on individual parts GP. For a beginner in this role what is your opinion? What was your rate when you started?

($36,958 is the median per capita income where I live, and $62,977 per household)

SN: I don't know what my parts department's actual gross per month, not sure how to find that information.)
