I personally consider this car as a technical prodigy, a design masterpiece. It is not just an "overpriced Toyota", this car is absolutely unique. LFA is, without any doubt, one of the best cars ever come from Japan. But I, unfortunately, have to admit LFA is incredibly overpriced judging from its performance. For that money I would rather take Aventador / F12berlinetta / MP4-12C / 991 GT3 together with manual-tranny Cayman. But still, I'm glad LFA actually exists - that's a good lesson for Japanese autoindustry.
I'm sure people hate on LFA simply because the "Lexus" badge on it. Silly stereotype. But again, this is no another glorified Toyota; LFA is extraordinary. You should have respected this car at least for its truly magnificent, glorious V10 sound.
I personally did not really care about Lexus in past years. Just like you, I thought it was nothing more but a bit more luxurious Toyota. And their design-language was absolutely booooring. But all that was until LFA was presented. In my eyes Lexus momently become a worthy impressive automaker, since I saw they can make something as schick-modern as LFA. And now even the rest of their model range is becoming impressive that before used to be boring! And their modern concepts: I honestly consider LF-CC is one of the most elegant looking cars ever made. And who knows what the future will bring us? I sincerely hope an LFA's successor! :D
