LO Ventures, LLC, doing business as Reefpoint Brewhouse in Racine, Wisconsin, contracted with Forman Awnings and Construction, LLC, for the fabrication and installation of an awning system over an outdoor seating area. After the system was complete, Reefpoint expressed concerns about the workmanship but did not give Forman a chance to make repairs. The brewhouse used the awning for two months and then had it removed so that siding on the building could be replaced. The parties disagreed about whether cracked and broken welds observed after the removal of the system were due to shoddy workmanship. Reefpoint paid only $400 on the contract price of $8,161. Can Reefpoint rescind the contract and obtain a return of its $400? Is Forman entitled to recover the difference between Reefpoints payment and the contract price? Explain in detail.3). Charity Bell bought a used Toyota Avalon from Awny Gobran Auto Sales Inc. The odometer showed that the car had been driven 147,000 miles. Bell asked weather it had been in any accidents. Gobran replied that it was in good condition. The parties signed a warranty disclaimer that the vehicle was sold 'as is.' Problems with the car arose the same day as purchased. Gobran made a few ineffectual attempts to repair it before refusing to do more. Meanwhile, Bell obtained a vehicle history report from Carfax, which showed that the Alalon had been damaged in an accident and that it's last reported odometer reading was 237,271. Was the 'as is' disclaimer sufficient to put Bell on notice that the odometer reading could be false and that the car might have been in an accident? Can Gobran avoid any liability that might otherwise be imposed because Bell did not obtain the Carfax until after she bought the car? Explain in detail. What does Gerald Morgan say about SGGK?
