Martin Hiett, a 58-year-old from Orpington in Greater London, won a £70,000 Ford Mustang Dark Horse plus the cash prize through BOTB’s weekly Dream Car Competition.
This is his second big win with BOTB, nearly four years after he won a £34,000 Hyundai i30N and £40,000 in a previous competition.
Mr Hiett said: “I feel on cloud nine knowing that the first one wasn’t just a one-off.
“I’ve had work colleagues asking how I managed to achieve this again.
“I’ve been looking at past pictures and watching other winners’ videos to try and get some useful tips.”
BOTB presenters Christian Williams and Katie Knight surprised him at work, where his colleagues applauded the announcement.
Mr Hiett was invited to sit inside his new Ford Mustang Dark Horse.
He said: “I’ve just sold the i30N and must admit I do miss the noise.
“The Ford Mustangs are a dying breed, so that’s why I played for it.”
The Mustang Dark Horse features a V8 engine, 449bhp, and a top speed of 168mph.
When the BOTB team opened the boot, they revealed the additional £50,000 prize.
Mr Hiett, who recently celebrated his 25th wedding anniversary, said some of the money will go towards a trip with his wife.
He said: “We’ve just been up to Scotland, so I think we’ll use it for another mini-break.”
Mr Williams said: “Surprising Martin again after nearly four years really did feel like déjà vu.
“The Mustang is a monster of a car and sounds incredible – the perfect upgrade from his old i30N.
“Having won once before, he never thought lightning could strike twice, but here we are.”
Ms Knight said: “To win such an incredible prize once is life-changing, but to win twice is just extraordinary.
“After recently celebrating his 25th wedding anniversary, it couldn’t have come at a better time.”
BOTB gives away a dream car every week, along with lifestyle prizes.
The company is currently running a competition offering the chance to win a luxury four-bedroom home in Surrey and an Audi Q8 Black Edition, together worth £810,000, for just £1.
Founded in 1999, BOTB has given away prizes to over 502,000 people, including £106 million worth of cars so far.
