Their cars are made in Belgium, Sweden, and more recently in China and Indonesia.
I spent a few months looking at cars before buying my MKS. Volvo was very high on the list. Just as you check the date on milk to make sure it is safe to buy, I was checking VIN's on S60's.
I just looked at 2016 and 2017 S60's and found VIN's for Europe and China. All of the Inscriptions are Chinese. I believe all S90's are built in China.
Something interesting I noticed in my search. Most of the time, the carfax says "car imported from Belgium 3/15/2016" or whatever date. For the Chinese cars, the carfax says "car imported 3/15/2016".
As much as Volvo wants to hide where it was manufactured, if the VIN begins with "L" it was made in China. "Y" means Europe, either Sweden or Belgium.
