Hi All,

Need advice… is the below a good deal?

I negotiated the deal today and they did take my deposit + reg + 1st month payment. However, was not handed any paperwork or don’t believe formal lease was signed but they did make me sign off on payment etc. The car arrives tomorrow and I haven’t seen it.

Anyways now I am thinking this isn’t a very good lease any feedback? And if not good any ideas on how to revise it given I haven’t taken possession or signed the actual lease?
