Inspiration and “Moto”vation:
As an artist (Groosh art website here), I wanted to bring an inventive design to my favorite marque without compromising the value of an original paint car, which this was not. Keeping it close to stock for a factory experience was also important. Through years of thinking and planning the inspiration would come from something that isn’t as obvious as painting the car a la the BMW art cars which I love. It would instead come from the influence of thousands of car magazines I’ve read since I was a teenager growing up outside Detroit.

By using the car’s 40+ year heritage and launch press articles to propel this concept, I gave the 928 the ability to “speak,” rather brag about itself, after gesturing come look at me. I felt it needed to tell the story of why Porsche’s success and their product line diversity demanded they devote an unheard of $200 million out of their $600 Deutschmark annual sales budget in 1974 to the development of the 928.

But why this particular 928?  It was clean, straight with low miles and good ownership history that showed new clutch and a/c converted to 134a.  Additionally the intake was polished which I had never seen before, the original first aid kit and tool kit were included plus it had the original steering wheel, stick shift knob and a Porsche Certificate of Authenticity.

However, this car was not original paint and the seats had been redone and have been again.  In a collector market where fully restored is highly valued and preservation cars are even more revered, this one was neither.  Full restoration didn’t make financial sense to me but this first year Euro spec ’78 928 deserved more.

The 928 was heralded as being one of the best supercars to ever hit the market while at the same time it was chastised for not being a 911.  A lot of transitions during the 70’s pushed Porsche to design a new car from the ground up such as the oil crisis, recession, aging product, emission and noise standards plus safety regulations thanks to Ralph Nader and Unsafe at Any Speed. This car was so important to the company’s success and their product line diversity that they devoted an unheard of $200 million out of their $600 Deutschmark annual sales budget in 1974 to the development of the 928.

When the 928 came out in 1977, the press loved it.  Articles in the United States alone from Car and Driver, Road & Track and Motor Trend praised the advanced V8 engine, forward design, GT handling and interior ergonomics.  The European press was no different.  In fact, the 1978 Porsche 928 won the European Car of the Year.  No Porsche before or since has ever won this honor.  None other than Paul Frère was on the judging committee for European Car of the Year in ’78 and is most noted for, ironically, his book The Porsche 911 Story which is a bible of one of the greatest sports cars ever made.

The convictions above drove me to buy and create the Porsche 928 Press Tribute Art Car.  As an owner of a ’83 911SC, ’71 911, 944 Turbo and 914s plus restorer and engine re-builder of a ’66 912 how could I ignore the genius of the 928?  I was tired of hearing lackluster appreciation for the car except from those who owned them.  So it had a liquid cooled engine in the wrong end.  So it wasn’t as raw as the tail wagger.   It wasn’t designed to be.  It was and is one of the greatest GT cars ever made as evidenced by the buff books that wrote about it.  I therefore decided it was easier to let people read for themselves rather than me try to explain it.

The art, design and build
This is not a vinyl wrap as commonly thought but rather 300+ pages 8.5″x11″ vinyl stickers, cut into thousands of pieces.  Each image was scanned from either the original 1970’s magazine bought on eBay or a book.  The scans were retouched and converted into black and white files then printed on bumper sticker material.

My vision was then to randomly cover the car as I worked. Random so to not detract from Tony Lapine’s brilliant design.  Each sticker, which is one of 32 individual pages printed in 10 sets, were carefully and thoughtfully placed.  Having the ability to change out damaged stickers over time that may result from peeling, weathering or scrapes/chips was the reason I chose not to clear coat the car when finished.  Additionally, I added three stickers from the movies that adorned the 928 and I liked: Weird Science, Scarface and Risky Business. The European Car of the Year sticker with proper logo from 1978, purchase through eBay in Europe, is in full color above each side marker light.

The two other major design components were the chrome headlight buckets and red vinyl seats.  The headlights were such a standout feature of the car that I thought they should pop.  However since they were plastic, I needed to find a chrome shop that specialized in the plastic plating process.  Paul’s Chrome in Pennsylvania has been in business since 1977.  I’ve heard of their high quality reputation for years and have seen their ads in Hemmings Motor News equally as long.  Their plating process involves a base coat of “paint” that has a metal/copper component.  The base coat conducts the electrolysis needed to adhere the plating process.  These headlight buckets are real metal chrome.  The red seats are a nod to my canvas paint series Black White Red while also being my favorite interior color.
