Just like in Upgrade Heroes, you will need to do some more Horizon story missions.
There's only 9 of them and you need to get 3 stars on all.
For Express Delivery, you will need 100,000 CR to purchase the business.
You will get a daily CR payout afterwards.
A lot of these missions involve the damage meter. Go over the damage limit and you fail the mission.
You will also need to park your car at the end of some of the missions, not run through the end point.
I'll note these in the list.The Challenges
1. Man and Van - Finish in 1min 30sec (Park; no damage meter)
2. A Box of Ducks - Finish in 1min 40sec (Park; damage meter)
3. Destination Not Found - Finish in 1min (Park; no damage meter)
4. Smash on Through - Finish in 1min 20sec (Park; no damage meter)
