370z nismo

[Idrinkbeer]

First off ,hi, im new here so forgive my lack of knowledge, I hope its OK to ask this , I have a customer who has offered me for sale their 2016 370z nismo, the car has just over 29000miles , in very dirty condition but to not being used for two years, so basically it needs a very deep clean and serviced, they are offering the car to ne at £20 k , i dont want to insult them but would like to be sure its a fair price.

I understand the 370 is more old school compared with today's motors, I have a gr yaris and a m240i but would enjoy something that won't age ( if ya know what I mean) so really im asking for the forums views on this .

Many thanks, and im loving reading up on these cars.
