NO
hell no.
Im thinking of it all the time (260rs with auto, lol).
depends on your parameters that you have to work within:
Im over 2meters tall= means dont fit in auto stagea very well let alone a manual stagea
had 9 knee surgeries and counting= means manual is an impossibility, pretty much
auto 260rs would be "faster" in traffic than a manual.
But Ive come to the conclusion Im better off sticking to my 30k budget for my Project: Steath Wagon, and get it into to Stagea 200 club. Have a happy car, with nice stealthy looks, modifications to mags, suspn, brakes, stereo, auto, engine, tuning. Dont need a 260rs to fulfill those (my) requirements.
Id be scared to "try" to add a automatic gearbox to a RB26dett brick.
