I just started collecting the data last week. But you can track the sales price at https://www.vindowsticker.com/sold
But yes, I would have the data for what your car sold for.
I built a free tool called VINdow Sticker that tracks 14,000+ 4Runners on lots right now with actual dealer selling prices — not just MSRP. See which dealers are marking up vs giving discounts, filter by trim/color/state, and find the best deal near you...
