hello
since GSRs and RS2s are the same car, minus some details.(pwr windows, locks, a/c, ayc, acd)
it would be very easy for mitsu to make GSRs lhd, or RS2s with ayc/acd etc.
besides, these are japanese car model names, once the EVO arrives in US, a RS2 might come fully loaded.
i don't think anyone in the US buys cars with no power windows anymore. yet, i hear the US getting RS2 model
