Buying a used car knowing there is a "service campaign"

[MattBaggins]

2. Sorry more detail

The car I am looking at has 27k miles but SOME cars of the model years of 2011 and 2012 have a service campaign to replace the timing chains due to a defect in them. I know from doing a carcheck that I also may still have an open recall on the fuel pressure sensor; but it is not major. The dealer selling the car is a Mazda dealer not a Nissan so they won't be doing the work.

Nissan is trying to downplay this as a service campaign, but when some owners are hitting 40k and having the chain break and blow the engine, it is a bit more serious then they admit. The service campaign is open until Oct 2015 so I have time on it.

I will be calling Nissan corporate tomorrow and have them run the VIN to see if the car is flagged for timing replacement and whether they will do it still.

I will go see the dealer Tuesday. I have my pitch.

1. The Juke has a particular crowd. People love it or hate it. Yours has been on the lot for 45 days. I am willing to help you and take it off your hands
2. Open safety recall
3. Serious service campaign for timing chain

I know they will offer me $500 for my beat up 04 Forester but I can go in with a print out of my autotraders.com $1500 offer.

How much could I realistically get them to go down on price?
