I sold two Q7s(traded in to dealer) for 5k less than I paid, am I foolish to do so or should I go the private party route? Selling to private party is too much of a hustle for me, though.
But good to hear your story.
It's all about how much of a hassle you're willing to endure.
For me, I made about $7500 per car in fix + Bosch money (about 25% of the cars I bought had already had the partial payment).
I have to pay back investors, cover shipping and other vehicle overhead costs, and also have to cover dealership costs. So a trade-in at a $5k loss would have meant no profit/slight loss on each car.
Thankfully, the used market is actually still decent (and I suspect will be better for Gen II PC cars than the SUVs), so I have been able to sell at or above my original purchase price, meaning $5-6k avg profit per car. A big factor was the warranty for all 3 buyers I've had.
For example, I bought a Treg at my local Manheim auction (no shipping cost) for $26k, got $9200 in fix + Bosch, sold for $32k. So net revenue was just over $15k and profit was slightly over $10k. That was (and will likely remain) my best performer.
The tougher cars to sell for me will be the higher mileage vehicles. I have 5 Q7s or Cayennes with 95k+ miles. Tough to fully recoup costs on those vehicles.
