Barris Kustom Industries, the birthplace of some of the most famous modified cars of the 20th century, looks set to close.

Self-proclaimed “king of the customizers”, George Barris moved his business to North Hollywood in 1961 after splitting from his brother and former partner, Sam. But according to the L.A. Times, the corner lot is now up for sale for $3.995 million and will almost certainly be redeveloped.

Barris, who passed away in 2015, is best known for creating the original Batmobile. After fellow customizer Dean Jeffries decided he couldn’t meet the TV show’s producers’ tight deadline, Barris finished the job in just three weeks, turning an old 1950s Lincoln Futura concept into a car fit for a superhero.

The metal fabrication was actually carried out by another shop on Barris’s instruction, but Barris was a canny businessman, and happily took the credit – and the cash. He retained ownership of the Batmobile, leasing it to the show, and eventually sold it for $4.6 million in 2013.

But the Batmobile was far from the only crazy creation to spring from the mind of George Barris. Here are a few highlights, plus a couple of lowlights to prove that even a genius can have an off-day.

The Munster’s Koach

According to Barris Kustom’s website, Geroge and his team built this creepy sedan for the 1960s TV show, The Munsters, in just 21 days. The 18 ft (5.5 m) hot rod was created by fusing three Ford Model T bodies and was powered by a tuned 289 cu-in (4.7-liter) V8 from a Mustang GT. Barris also built a second car called Drag-U-La for the same show, and when we say it was a real coffin on wheels, we’re not kidding.

The Car

Hardly George’s most colorful creation, this modified 1971 Lincoln looks like some kind of novelty inflatable. But it’s still the best thing in the awful 1977 movie of the same name in which local Sherriff, James Brolin, investigates a mysterious spate of hit-and-run deaths.

Sidewinder

With a bike wheel up front, and a pair of DC-6 passenger plane wheels at the back, this terrifying chopper trike must have understeered like a Citroen 2CV on a frozen Scandi lake. Wheelie bars at the rear stopped it flipping over when you unleashed the 400 bhp Buick V8, which sat across the frame in the footwell, getting cosy with your shins.

Pontiac GTO Custom Convertible

Pontiac’s comeback GTO coupe was panned for looking too boring, but you couldn’t say that about this one-off convertible that Barris fitted with Mercedes-McLaren SLR-style doors, a chopped screen and ostrich leather upholstery. Not the great man’s finest work, but at least it was better than his Prius…

Voxmobile

When UK-based guitar and amp manufacturer Vox contracted Barris to build a promo machine, George turned his imagination dial right up to 11. The twin giant Vox Phantom guitars were fakes but it featured a trio of working amplifiers capable of powering 32 guitars and a functional Super Continental organ at the rear.

Wagon Queen Family Truckster

The hideously kitsch fictional car driven by Chevy Chase’s Clark Griswold in National Lampoon’s Vacation was really a 1979 Ford LTD country Squire, but modified by Barris to mock Detroit cars of the time.

SuperVan

Not seen 1977 Vansploitation flick, SuperVan? Me neither, but since IMDb lists “wet t-shirt” and “nipples visible through clothing” as plot keywords we can presume its not Scorcese-grade stuff. Still, the Dodge Tradesman-based lead vehicle, which Barris had originally called “The Love Machine” (what, with that much glass?), looked so futuristic it was even reused as a public bus in Back To The Future II’s imaginary 2015.

Before Barris became famous for his TV cars, he was one of the biggest names in Southern California’s 1950s and ’60s custom and hot rod scene. Clarence Catallo’s ’32 Ford coupe had already been worked over by the Alexander Brothers in 1959, but it was Barris Kustom’s roof-chopped incarnation of Silver Sapphire that was immortalized on the cover of the Beach Boy’s Little Duece Coupe record.

Chevrolet Aztec

Based on a 1955 Chevy, but incorporating custom tail fins from a Studebaker Hawk, DeSoto bumpers and an incredible cantilever roof, the Aztec was built for (and with the help of) Barris’s friend and roommate, Bill Carr.

After Carr sold it in 1961, the Aztec’s story gets weird, and involves bank robbers, a murder and an FBI drugs bust. But it was restored in the 1990s and recently cropped up for sale with Mecum.

The Hirohata Merc

One of the most influential custom cars of all time, this one came about when Bob Hirohata asked George and Sam Barris to modify his two-year old 1951 Mercury coupe. The top was chopped and the B-pillar removed, making it look like a hardtop, and almost every other bit of metal on the car was re-shaped in some way. Inside, the dashboard was hand-painted by legendary pinstriper Von Dutch.

While the famous Barris shop might be closing, it looks like it might live on in spirit. George’s daughter, Joji-Barris Pastor, who has handled much of the running of the business for the last 20 years, told the L.A. Times that the garage’s historically significant contents will be boxed up and moved to another location which will eventually be open to the public.
