David MacNeil, a Republican megadonor and the billionaire founder of WeatherTech, sold a waterfront mansion in Fort Lauderdale for $34 million.
The price marks a 32 percent price cut from the property’s 2024 listing price of $50 million. The deal for the mansion at 84 Isla Bahia Drive was first reported by the New York Post and has yet to appear in public records. The buyer is unknown.
Chad Carroll with Compass had the listing, and Brett Bass with Bass Realty and Investments brought the buyer.
MacNeil founded the car accessories giant WeatherTech in 1989. He now has an estimated net worth of $4 billion and a car collection worth $400 million, according to Forbes.
He is a frequent investor in South Florida real estate. In 2024, he bought the 2-acre oceanfront compound at 1120 South Ocean Boulevard in Manalapan for $38.5 million. In 2025, he bought the adjacent 1.5-acre estate at 1140 South Ocean Boulevard for $55.5 million. In February, he bought the oceanfront mansion at 1940 South Ocean Boulevard for $68.3 million, bringing his total spend in the enclave to $162.3 million.
He has donated at least $3 million in support of President Donald Trump since 2016, Forbes reported, including $1 million for the 2017 inauguration and over $1 million during the 2024 election cycle. Trump tapped MacNeil in January to serve as a chair of the Federal Trade Commission, and his appointment is awaiting confirmation.
MacNeil bought the half-acre waterfront Fort Lauderdale property for $5.5 million in 2013, according to property records. He built the 11,700-square-foot mansion in 2020, and it has five bedrooms, eight bathrooms, one half-bathroom and 300 feet of waterfront, records and the listing show.
The sale marks the latest pricey deal in Fort Lauderdale in recent months. After rapid price growth in the city’s luxury market during the pandemic boom, deals have slowed in recent months, often requiring price cuts to get done.
In February, Greg Clark, the former CEO of cybersecurity giant Symantec, bought a waterfront mansion for $21.5 million after years on the market and a $4.5 million price cut.
