Given the literal question they asked was about LR RWD vs LR AWD- yes I definitely think they were interested in that.
Not really.
5.3 0-60 is certainly respectable and will spank most minivans and suvs and econoboxes (though still not all of em)... but there's TONS of sport sedans, pony cars, hot hatches, and then actual sports cars out there it's definitely not "considerably faster" than
Contrast with the LR AWD that'll beat the vast majority of those (and nearly all of em with the 2k acceleration boost) (or the P3D- which if you can actually find one in the color/wheel you want is obviously the way to go over the LR AWD+)
Percentage wise, those "tons" of other fast cars make up a very small percentage of the total cars. So you're still faster than 98% of the cars on the road with a SR+.
