Dubious had no experience with "petrolenia" (the hobby of collecting old-fashioned gasoline pumps, oil cans, gas-station equipment, tools, vending machines, and supplies--an off-shoot of the old-car hobby) but he contracted to purchase for $8000 a 1930s-era Sun Oil gasoline pump from Seller. Two weeks later, Dubious and Seller met with a state Soil Conservation inspector to discuss the condition of the in-ground gas tank Dubious wanted to use. Seller said to the inspector, in Dubious' presence, "The pump pushes a good 10 gallons a minute; it's sure worth $8 grand." The underground tank was approved; Dubious installed the pump, but it only pumped about 1 gallon a minute (uselessly slow), and therefore its value was only about $1000 as a conversation piece.
When the pump proved useless for practical purposes, Dubious sued Seller for rescission of the contract. May Dubious avoid the contract?
