I really fail to understand why people buy a performance car, disregard what the manual says, and try to nickel and dime clear recommendations. 91 or 93, depending on your state...
I've had an E36 M3, 2012 135i, and now an F97 X3Mc. The Supra has gotten my attention like no previous Japanese sports car has. I'll get a chance to drive one (2021) soon; I hope. The collaboration may have gotten the best of both worlds. We'll see.
