Former GM of car dealership asked me what it'll take to get me back.?

I started as a sales consultant in November of 2016 at a place over 1 hr from home. You work all but 6 days out of a month if not less and 9 months out of the year you work 8am-8pm at least. I worked on the used car half of the lot and had a couple of good months averaging 12-13/month over the 6 months I was there. I started at a smaller lot that sells almost new cars exclusively and I started with 7 sales then 10 and now I've got 4 out with 5 lined up for this coming week, not counting what I get in the near future. The GM of the former store texted me tonight asking how I was doing then when I asked him how he's doing he said missing having me there and what will it take to get me back. I'm happier where I am now, and working less hours. I'm not making crazy money yet, but the future is looking bright. The other store I was treated like **** by finance and managers alike save for a couple of them. I'm starting to get Internet leads, and phone leads and a couple cheese deals that are ready to go. What should I tell the former GM? I'd like to make it into finance eventually as they earn quite a bit more. It costs about $4k more to work at the previous place per year than my current place. Should I ask for $10k bonus, set my own schedule, and contract that in a year I'll be starting in finance if I so choose? I feel like it is reasonable since I made $18k profit for the company I'm at now just last month. Should I reach for this crazy demand or be more reasonable?
