I own a 2015 BMW 328d xDrive wagon, which I bought new. It has 230,000 km on it. As a trade against a new BMW, local BMW dealers are offering between C$4000 and C$8000, which seems low. I know I can probably get more privately, but with extra work. I am hearing anecdotally that there are people who covet this combination of: made in Germany, wagon, diesel. My question is: where can I find these communities, so I can gauge interest in the car and its value? I am in Ontario, Canada.
