Arguable at best. The reality was Studebaker could not produce the Avanti in appreciable numbers to begin with and sales were lost along with what goodwill and publicity they had. It’s all well known and no reason to go over that.
The Ford Mustang was often marketed as a secretary’s car…six cylinder and economy oriented where the Avanti was marketed as an upscale vehicle. Ford was looking for mass sales while Studebaker looked the Avanti as a halo car…sales were certainly wanted but also to bring in foot traffic to sell Larks and some Hawks…Studebaker’s bread and butter cars. The Lark series were the secretary cars and economy minded buyers. The Avanti was more directed at the Buick Riviera, Ford Thunderbird and Pontiac Grand Prix market.
