The Porsche 964 was produced from 1989 through 1993. Yes, this is a Porsche 911. The other numbers, 964, in this case, simply refer to the kind of 911 a given Porsche is.
In case you were wondering, people in the Porsche community like to refer to 911's by their sub-model three-digit number because the term 911 can be so vague, seeing as how the model just celebrated their 50th anniversary with the debut of that hot new thing called the 991.
Getting back to the topic, The Porsche 964 marked a significant overhaul in design and engineering from its predecessor, the 930. The 964 was unveiled as the Carrera 4 for the first time, the "4" referring to all-wheel drive, a first for Porsche models. The Carrera 2, a rear-wheel drive version, was debuted a year later. Updated aerodynamics were also integrated into the beauty of the 964, which resulted in a lower drag coefficient of .32. The Porsche 964 introduced coil springs, ABS brakes, and power steering as regular elements into their flagship's lineup as well.
Although Hank's Porsche typically makes 911 enthusiasts cringe with its regular imperfections and harsh driving conditions, one thing remains true: it completely reflects its owner. Much like Hank Moody himself, his 964 looks like it needs a shower, damaged inside and out, and is often pushed to its performance boundaries (by speeding away from the boyfriends and husbands of Hank's night calls).
However, just like we see Hank redeem himself by doing the right thing, helping out his friends, and revealing his lonely big-hearted soul once in a while, his Porsche 964 is no different by providing its race-inspired German engineering and design that will always remain the golden standard and never go out of style, no matter how long it has been since the last time it had a good wash.
