Au contraire! How about this from a client whose sports car turns heads with a pair of 6' Adrian murals:
Or this from the Hearts in San Francisco project:
Here are some testimonials retrieved from the glove compartment of my Volkswagen art car--
The Dragon Vespa scooter is an even bigger hit.

The first time on the road in my Rolling Surf art car. a bicycle messenger shot past, did a double take, and climbed clear off his bike to bow and applaud . Big rigs toot. Many smiles. Lots of thumbs up.
Even Adrian Studios' graphic design is not overlooked. From Monica --
These testimonials not only vouch for the quality of the artwork of Adrian Studios, but they point to something else as well. I once bought a rare Alvis automobile from a concours exhibit. I naturally talked with the owner about availability of parts, haggled over price, inspected its repair record, and so on. He then said something very peculiar. Something that dispensed with all pretence of practicality. "With this car," he said, "you'll always have friends."
Fair weather friends, you say? Perhaps. But it always felt good to have that extra TLC while driving across country. And it made one feel positively popular to pull up onto the winners' platform at Pebble Beach. So it is with art from Adrian Studios. You'll have a winner, and you'll always have friends.
Most importantly, however, it is the chi - the spirit and intrinsic value - that generates all this enthusiasm and makes the work worthwhile to create and to own.
