Granturismo GmbH Managing Director Udo Satzer has sought a temporary injunction to force Ferrari to deliver the cars. The case will be heard in a Frankfurt court on Tuesday, July 8.
Granturismo has sold about 60 vehicles a year since it became a Ferrari dealer in 1997. It is one of the largest Ferrari dealers in Germany, which is the brand's second biggest market after the USA.
But Ferrari's German importer, Ferrari Deutschland GmbH in Wiesbaden, stopped supplying Granturismo with cars earlier this year following a dispute.
Satzer says the disagreement stemmed from Granturismi's refusal last autumn to sell Maserati models because of alleged defects. Maserati is part of the Ferrari business unit within Fiat SpA.
In February, after the two sides failed to reach an agreement, the German importer cancelled Satzer's dealer contract.
The court must now determine whether Satzer is entitled to bonuses, commissions, sales support and advertising grants of approximately 350,000 euros that the dealer says are still owed.
In addition, Satzer claims that approximately 150,000 euros for warranty -- and guaranty jobs, which had already been approved, are still outstanding.
"In total we will fight over a few million euros," Satzer said.
The dealer says he can prove that over the years Ferrari retained at least 60 sports cars that it had agreed to supply to Granturismo.
Satzer said Ferrari should "compensate me accordingly for the lost amount."
"It was my team which turned Hamburg into a lucrative location for Ferrari,'' he said, "and all we get for it is ingratitude."
Satzer said he plans to fight for a new dealer contract.
Ferrari Deutschland GmbH declined to comment.
