Pistons Owner Tom Gores Buys $100 Million Mansion!!!

One of the best properties in all of Los Angeles just sold ... for a cool $100 mil, TMZ has learned.

Detroit Pistons' owner Tom Gores snagged the Holmby Hills estate Thursday. The place is spectacular ... 30,000 square feet, 10 bedrooms, 20 bathrooms, a 10 car garage, ridiculous pools, including an indoor waterfall that drops into a lap pool, beauty salon, wine room, massage room, movie theater ... and on and on.

The master suite alone is 5,300 square feet!

It's the second $100 million sale in L.A. ... back in August the Playboy Mansion, also located in Holmby Hills, sold for the same amount.

Gores kept it all in the family. He was repped by real estate agents Tiffany and Christy Martin, his nieces, and sister Samira. All 3 agents are with The Agency, which by the way also sold the Playboy Mansion.

The property used to be owned by Barbara Streisand back in the day, but years later it was razed and the new house was built.
