Tips for Scoring Ultimate Skill Chains

So I feel like I have scored at least 7 Ultimate Skill Chains, but it hasn’t regisetered that I won the Porsche.

I have checked my garage, not there.

I checked the Forzathon checklist, not blacked out.

So does anyone know why I haven’t got it?

If not, what are some tips to get Ultimate Skill Chains so I can get it?
