My question is, what is the difference between the standard variable assist steering and the ZF ServoTronic II. Is it more effort to steer like a sports car or a different ratio? Reason I am asking is because i want the AWD with navigation and V8 but am worried the ZF steering is gona be too sport tuned. My 2000 STS's steering is perfect, its a little heavier and more effort required than the Devilles and the SLS but not too much so where its like my Z28. Any help would be appreciated I have been so busy I havent even looked at one in person or driven one even though I am obsessed with the new STS. Thanks in advance.
