Not much to tell really, it has a nice power delivery, great noise, seems a little highter pitch than the 350z and lots of room, especially for the little one.
I dont think they will launch them in the UK though as Infinity is not something i can see them bringing over here, however you can always import one.
From Nov 2007 Autocar
Infiniti will not be launched in the UK until 2009 due to setbacks in establishing a dealer network. Although no hard date had been set for the brand’s introduction, original estimates put the launch date at the end of next year.
Problems with finding a partner in the UK to oversee the creation of a dealer network have led to the delay. The quality of the dealer experience is an important part of Infiniti’s plan to woo buyers from established premium brands such as Mercedes and Audi, as Lexus has done, and it does not want to risk making any mistakes.
