Buying High Mileage 2017 Si

I'm looking at buying a 2017 Civic Si Coupe for ~$10,000 Cad ($7,500 Usd). Sounds like a steal at first, but the catch is it has 375,000Km on it. I am yet to go look at it in person, but from what I hear it runs and drives like new. What should I look out for when buying this vehicle? Should I avoid buying it?
