What you want to do is find out what the adjusted cap cost is on the RDX which should be around the mid $34"s then have them work it from there. The miles you are looking at will ad about $50 dollars a month maybe a little less. The term is good, now for the money down. This lease requires $2999 due at signing PLUS inceptions which depending on where you are is probably from $1200 to $1500 dollars. so you are putting down about $2500 less than required by the program which will ad about $70 so now lets go to the tech pack which will add about another $80-100 dollars. so you will probably be looking at about so if you add all this up you will probably be around $600-$620 a month + tax. Amazing how you go from $400 to $600 huh. Now I wont tell you how I got here but you will probably be around $550 a month + tax. If someone comes in with a number that is a lot lower then they are probably low balling you to get you in and don't deserve your business. This is a pretty fair price for this lease program and the miles and money you want to put down. Good luck and if you have any questions then let me know.
