With all the cries for more advertising, has anyone estimated how much a comprehensive ad campaign might cost? Has anyone here managed a national advertising campaign?
Advertising runs about 2 to 7% of a company's sales. Let's say Piaggio goes wild and spends 10%, or $4.2 million of it's 2009 gross sales, on an ad campaign. That may soulnd like big bucks, but cheap (other than prime programs) national TV spots run about $100,000 for 30 seconds. That's 42 TV commercials. They could run one a day for 6 weeks, in less than prime time, and the budget would be depleted.
What demographic will you go for?
Harley made inroads in the under 35 market, but not as a daily ride, but with lower priced ($8,000) bikes using themes such as
"About six bucks a day. Cheaper than your smokes, a six-pack, a lap dance, a bar tab, another tattoo, a parking ticket, a gas station burrito, bail, cheap sunglasses or more black T-shirts." In short, still going for the "rebel" crowd, but at a lower price point. Is there a Piaggio product that can make inroads into this market?
What "sizzle" is Harley selling? Is this indicative of a "practical, daily ride"?

We are preaching to the choir here. Could it be that most of the people with wants and needs like the US members of MV already have a Vespa? How much ad money would it take to stimulate similar wants and needs in the remainder of the US population?
Unfortunately (for the scooter industry), high fuel prices in the US did not last long enough to sustain a shift to scooters as daily rides. Coupled with sufficient discretionary income at the time, it simply fueled a fad. Now you have "reasonable" fuel prices and less willingness or ability to make discretionary purchases.
In the US, the PTW is still seen as a recreational vehicle. Can you use it to go to Costco, take the kids to soccer practice, ride to work in all weather, etc? Can a company with $42 million in sales budget enough marketing dollars to create a culture shift? Harley didn't try to do that. They have just been adjusting their product line to make their more affordable products visible to a wider audience of recreational, "escape" customers. But, when you have products that range from $8,000 to $40,000, you have room to maneuver. And, Harley has not tried to cause a culture shift, but has just made the Harley culture available at lower prices.
