Well if the Lexus LF-A ends up being like the current Acura NSX (which i mean, is quick and nimble on the track AND can manage the high mileage like the Acuras and Lexus' do now...then you'd have a winner. For those who want a daily driver, but don't want the super high maintenance...then you might have something here.
But you build a car with a high enough price tag, and the performance/luxury to back it up with a decent brand name...and BAM. It'll sell.
I mean...really, you give the Murcielago were a Honda Murcielago, it wouldn't sell. People are very materialistic these days (And I admit, i am somewhat materialistic...)
If it weren't the case, then Lamborghini, Ferrari would all be out of business. Prestige is a big thing...Lexus has earned it...so a 220k Lexus isn't a stretch for them to do it.
I'm sure here we all like Acura to an extent, but until Honda/Acura shape up with their cars, and finally produce something to compete in a level higher than the RL....then maybe they can regain it.
