People don't buy these cars to drive slow. Being so new you would think most of these kms are highway but you never know. Usually the miles on these are a little more heavy than on say a corolla or something of the same year. As long as you get it checked out by a proper mechanic you should be in the clear. But its an unknown platform really as they haven't been out long enough to see if they will last like 300k miles or something.

Well, it certainly isn’t a liquid or gaseous vehicle..

90,000km is relatively new for a Subaru. It should be okay, don’t expect it to be a pocket rocket. 

Love my 17 BRZ, bullet proof so far. 90,000KM? It will take me 10 more yrs to get there. Winters in Canada, she is of the road. What does the dealer want?
