The S-FR II concept picture is growing on me. I would definitely consider this if Toyota goes through with production. Considering that I have been scouring the market for Miatas and Mr2s recently. I would really love to see a true lightweight contender to the new Miatas and then the comparison that follows.
As for this High power RWD Sports Car versus a FWD car, I feel each has its place in the auto world whether economy driven or performance driven. I'll also say this, I would much rather have a 'FWD Track Car' then a high horsepower 'RWD Sports Car'. The end of the day is I would not give too much care for a track car and I would abuse the cap out of it, versus having a nice RWD Sports car. The end of the day, the amount of maintenance money you would have to throw at the RWD car to keep it health especially if you track it could go into many other things then just upkeep such as Track Days, HPDE, Autocross, Race Series if you have a license, Performance parts, etc.
I unfortunately don't have unlimited funds to be able to enjoy a really nice car. I made a decision and my wife backed me up with it when I decided to do away with a daily driver in order to have a track car. This actually brought me to this thread because I have been looking at Miatas and would love to have another car besides the Toyobura and S2000 to look at.
Now being in the market like I said, I was looking at Miatas along with MR2s (the first and third Gen ones). I am weighing the options compared to purchasing the new Miata versus finding a used one. I would really consider this new concept if Toyota comes through with this.
