Personally I think there is no way to know exactly if you have a good deal or not, given the limited number of folks who can get the deal. Unless they are posting. And even then, the situation will vary by time , dealership and personnel.
Absent of that, I would see what the deal at invoice is WITHOUT the lease deal, taking into account all incentives available, and knock of say $1000. If you're around there or better, I'd say you would have a pretty nice deal.
There's no magic figure - like $60,102 is a good deal, and $60,103 is a bad deal. You also need to factor in your time jumping here and there, plus the possibility of losing the car you are interested in. Sometimes you need to decide, yes, I'm happy now, bite the bullet, then just enjoy the car - and NOT look at what someone else was able to get one week later.
