The problem with Foxtons marketing

Foxtons have been doing some aggressive (and technically impressive) guerrilla marketing lately. However I wonder about their overall strategy, and a lot seems to be timed with their well publicized IPO intentions or in an effort to score a private equity buyout.
Looking at the Foxtons video advert, reminds me of a conversation I had with a friend recently who reminded me that you hardly ever see anybody over 30 working at Foxtons; which is great for sex appeal, but not so good when trying to sell property in London. In essence, Foxtons appear to be trying to appeal to a younger, more tech savvy demographic, but the problem is that most young tech savvy people in London can't afford or don't buy property in London. And the few that can and do, well why would they use Foxtons, given their less than stellar reputation.

I'm going to assume that the company makes the bulk of their revenue from lettings. I'm basing this on the fact that they're so obviously appealing to young people, and young London may not buy, but they sure do rent.
This poses another problem since a lot of landlords - especially those that have significant portfolios - are dubious about doing business with the big F(u), a company that has been known to and caught on camera forging landlords signatures. Nevertheless, the company has been making strides to clean up their act, and joining the Ombudsman Scheme for Estate Agents was definitely a big step, although they're not yet members of the more influential and credit worthy National Association of Estate Agents.
