Interesting....the general thrust seems to be it is OK so long as it it is very subtle/discreet, which is my view. I recall a saying - the larger the logo the lower the self esteem! l still struggle a bit because of the "look at me" factor, hence the need for significant discretion. Although there is a pair of cuff links I do like (not the trident shaped ones) I can't help feel it is still showing off, if I wore them, say, at work, so they are still in the shop.
For now I just have the official mug, which at £17 (Christmas present from the wife) is of astonishling poor quality, with neither the handle, nor Maserati, on straight - good old Italian hand made craftmanship!
