The 1974 Lancia Stratos HF Stradale is a Treasure Car hidden in the Sotoyama region of Forza Horizon 6, tucked against a small building on a mountain road that runs past the Tateyama Kurobe Alpine Route. The in-game clue points you to a snowy slope rather than a parking lot or city street, and the car sits in plain sight once you're on the correct road.

Where the Stratos is parked in Sotoyama
The clue text reads: "A legendary Lancia Stratos has been spotted abandoned near Tateyama Kurobe Alpine Route in the Sotoyama region." That hint narrows the search to the central mountain road of Sotoyama rather than the larger peaks to the north or the ski resort to the east.
The exact spot is on the smaller mountain route that runs between the ski town settlement and the Hakusan Mountain Lodge player home. The car is not on a peak, not at a race start, and not inside the alpine route's glacier walls. It is sitting on flat ground next to a wooden building, just off the asphalt, with a ski trail dropping down behind it.

Stepwise route from Hakusan Mountain Lodge
Step 1: Fast travel to the Hakusan Mountain Lodge player home in Sotoyama. If you don't own it, fast travel to the Tateyama Kurobe Alpine Route discovery point instead and skip ahead to Step 3.

Step 2: Leave the lodge and head west along the main mountain road. This is the road that cuts across the region rather than the loop heading north toward Lake Nukabira or Snow Monster Forest.
Step 3: Continue west through the Tateyama Kurobe Alpine Route Speed Zone. The towering snow walls are a clear visual marker that you're on the right stretch.
Step 4: Stay on the road past the speed zone and watch the right-hand side. You're looking for a small building paired with a speed limit sign at the roadside.
Step 5: Pull off next to the building. The Stratos is parked alongside it, near the base of a ski route descending from the mountain above. Drive into the car to claim it.

Use the drone if you overshoot
If you keep missing it on the road, switch to the drone from the pause menu and fly along the same stretch from above. The Stratos has a distinctive wedge shape and bright body color that stands out against the snow, which makes spotting it from the air much faster than another driving pass.

How to confirm you got it
Driving into the Stratos triggers the standard Treasure Car claim animation and adds the 1974 Lancia Stratos HF Stradale to your garage immediately. The Treasure Car entry in your Collection Journal will tick off, and the clue photo disappears from your active objectives. If none of that happens, you've driven past a different abandoned car or scenery prop and need to keep moving west along the same road.
