In total, O'Quinn is estimated to have won $1.5 billion for his firm. The firm went through several names during the 1990s, among them O’Quinn, Kerensky & McAninch; O’Quinn, Kerensky, McAninch & Laminack; and O’Quinn & Laminack. Pirtle became a name partner in September 2001, and the firm name became O’Quinn, Laminack & Pirtle. According to a 2006 article in "Forbes", O'Quinn's firm had pending cases against stock brokers and hedge funds for shorting the shares of weak companies, and against Ford for rollover accidents caused by the Ford Explorer. In the past decade, O'Quinn won, through settlement and/or verdicts, more than $20 billion for his clients. Around 8:00 a.m. on October 29, 2009, O'Quinn was driving his Chevrolet Suburban on Allen Parkway in Houston, Texas in rainy weather when the vehicle struck a curb, crossed a grassy median and three lanes of oncoming traffic, and crashed into a tree. Both O'Quinn and the other occupant, his assistant, Johnny Lee Cutliff, died instantly of blunt force injuries. Neither man was wearing a seat belt. According to Capt. Bill Staney of the Houston Police Department's Vehicular Crimes Division, the Suburban's crash data computer showed the vehicle traveling at 76 mph just before impact, and that O'Quinn never applied his brakes. The posted speed limit on that section of Allen Parkway was 40 mph.  O'Quinn attended an exhibition of Duesenbergs as a child at the Sam Houston Coliseum, to see what his father called "the greatest car ever built." In 2003, O'Quinn saw a 1932 Duesenberg Durham Tourister for sale at a Houston auction, at which he bought 14 cars that day including the Duesenberg for $405,000. O'Quinn maintained an extensive collection of cars. The collection had a total value of over $100 million and included at least 618 cars in 2006, and by the time of his death in 2009 he had collected about 800 cars. The collection included: seven Duesenbergs; the 1911 Rolls-Royce Silver Ghost featured in the film "Titanic;" John F Kennedy's 1962 Lincoln Continental Bubble Top limo, and a 1937 Bugatti Type 57 Atlantic.
