I’m looking to buy a 2017 A4 2.0t with 87000 km on it. From the pictures and videos I’ve seen it seems good and nothing wrong with it. After negotiating with the dealer I managed to get a price of 21500 cad all in. I’ve seen the Carfax and it seems to have been serviced well and it’s only had 1 owner. I’m wondering if this is a good deal and should I expect issues and what should I prepare for to not run into many issues.
Any advice would be appreciated, thank you.
