well, I think I figured out how barn finds work… and like others I’m sure that have tried, it’s all “in theory” though, until we hear differently.
It’s all based on driver’s mileage. How far you’ve driven in-game. My friend started playing and he went through it similarly to the way I did it -
discount signs - TOP PRIORITY. We hunted those things down.
He also stopped at the “hotspot” thingies, like me, and started doing those PR events.
however, he hasn’t started to “farm” those yet (it’s a great way to make $$$ with the skill challenges/sponsorships) and his popularity is only #247.
He has unlocked 5… yes FIVE of the barn-finds already!!
Mercedes Gullwing
Plymouth 'Cuda
Bugatti
BMW M1
Aston Martin DB5
literally, at a “mile-marker” they unlocked. I can’t remember the details right now, but it had nothing to do with races won (he’s only won the first tutorial ones), or anything else either I bet. Just driving. It also wouldn’t surprise me if it goes up exponentially. It would explain how it took me 1200 miles (exactly!!) to get the Shelby Daytona.
It seems the first 5 cars may go in a random order. However, I’m thinking the
Jaguar
Aston Martin DBR1
Shelby Daytona Coupe
Ferrari 250
actually come in a set order. And I will say, my four favorite cars to drive are all barn finds!
hope this helps, although, probably about 2 years too late. I’m going to play the game on another profile, with no Forza history, and see exactly if miles is the only thing to do with it, and IF it matches up to the miles driven my buddy and I have had previously. If that’s the case, I’ll post it here.
