So was the sponsership of the Oak racing team by Morgan at Le Mans a success.
Andy, I'd suggest that the key to answering your question is how you define success.
If the exercise was designed to raise the profile of Morgan, then, even if one new person is aware of the brand, I'd suggest it was a success.
If, on the other hand, you had hoped for a Class win, 40-years after the last one, then no, it wasn't a success.
For my part, I am quite ambivalent about MMCs actual involvement in the Le Mans 24 Hours; perhaps like most British football supporters, I don't expect a win but had we done so, I'd have been thrilled (does that make me a fair weather racing fan?
). However, I always support the company putting themselves forward, in relevant activities, where they are able to bring the company name (and by default the product range) to an audience who may not be aware of what is on offer from MMC.
