I think the LFA kit probably only exists because Mr Tamiya has one... it's well-documented that the plastic model as opposed to RC side of the business is very much a matter of personal enthusiasm and commitment from the senior management. Given the extraordinarily high quality of the engineering and manufacturing skills on offer at Tamiya, it's the only way to make sense of the choice of subjects (why not a 1/32 Mustang? Why a 1/48 Swordfish?... ) They aren't driven by market research, but by passion and enthusiasm. Fujimi and Aoshima are the guys who are going step by step through the list of exotics that I want to buy. I wish that Airfix and Revell (Germany) would do the same through the UK Top Gear "Dream Garage" for Europeans. But Mr Tamiya makes what Mr Tamiya wants to make....
