Wow! Must be a Canada thing, the high used vehicle prices!
Right now, many items for sale, be it homes, property, vehicles, are still in the "honeymoon" phase of pre-pandemic high prices. It is going to be about 3-6 months before the prices adjust to where they need to be. Once these greedy people sit on inventory long enough you'll be able to call the shots. Even in USA the last few years has been terrible as a vehicle buyer. It has seriously been better to buy new than slightly used for at least the last 5 years. I think things are going to change a lot in the market soon.......
BTW, when my Titan 4x4 Crew Cab was 2 years old with 22K miles I paid $22,000 + taxes (10%). It only has 71K miles on it. $20K for 149K miles....yikes!
