That's a tough one Dullah. I love leather scents more than any other genre and have tried most of them.
The true hyper-realistic leather scent in terms of a chemically treated brand new car interior doesn't exist in perfumery (Tuscan Leather is one of the closest, but still not a perfect match) as 90% of the "leather" scents are interpretations of what various types of leather smell.
Not sure what to recommend for a cool, chilly aspect coupled with a car leather interior style of leather scent. I know that there's not much out there that would fit this bill. As for the cleanest and freshest leather, however, I may recommend Odori Cuoio as it has a soapiness to it. I'm not sure that I would describe the leather note as car interior leather however.
Interested to see what other recommendations pop up, and no, the classic leather scents that always get recommended (Knize 10, CdR, REL, etc.) do not resemble new car leather in any way IMO even though they are great scents in their own right.
