Aston Villa footballer John Carew has told a court he was "tricked" into trusting a man accused of duping him out of £200,000.
Birmingham Crown Court heard the Premier League striker paid £100,000 to Richard Esprit, 43, for a Porsche Cayenne Gemballa which he never received.
The Norwegian footballer told jurors he had agreed to pay Esprit a further £50,000 for modifications to the car, which he wanted to be pearl white, with a "lipstick" red interior.
He said Esprit, from Staines, Middlesex, promised to have the car delivered to him in Norway but "disappeared" when the vehicle did not arrive.
Mr Carew told the court he transferred a £20,000 deposit for the white Porsche to Esprit, followed by a further sum of £80,000.
He said he instructed Esprit to sell his BMW M6 for him and keep the proceeds of the sale to fund the modifications he wanted to make to the Porsche, including a more powerful engine.
Mr Carew said he began to get "suspicious" and "frustrated" about waiting so long for the vehicle to be delivered, after initially being told by Esprit in March 2007 that it would be ready in around eight months.
The footballer said Esprit gave him a black Porsche Cayenne Gemballa to use free of charge while he waited for delivery of the white version of the car. He said: "That tricked me into trusting him."
After having problems getting hold of Esprit for a few months, Carew said the pair met at the Dorchester Hotel in Mayfair, London, in April or May 2008.
He said: "He (Esprit) said the car was about to arrive and I started to get happy, all smiles again. Even though it had been suspicious, I started to believe it was going to happen."
He added: I'm a positive person and I still believed, even though it was kind of chaotic, I chose to believe that I was still going to get my car."
But Mr Carew told the court that the car did not arrive in Norway and communications with Esprit ceased.
He said: "When I went to Norway I couldn't get hold of him anymore and I haven't spoken to him since. No car appeared and I couldn't get hold of him. I tried for quite a while...he disappeared."
The court heard that while he was waiting for the white Porsche, the footballer bought a second Porsche from Esprit - a black 997 turbo - for £92,500 but returned it to the salesman after problems with the registration paperwork. Mr Carew told jurors he never received any money from the resale of the black Porsche.
Esprit, of Ouseley Road, denies three counts of fraud and two of the theft, allegedly committed between March 2007 and April 2008.
