Hey guys, I'll be ordering a Model S in the near future and I currently own a 2014 BMW 550i M Sport. For those of you who may not be that familiar, it's the same twin turbo V8 that's in the M5 just not near as much HP and other enhancements. My goal is to attain (or close to it) a similar driving experience with regards to handling and performance. I'm not thrilled about spending the extra money on the P85D so for those of you who are familiar with my car or equivalent, I wanted to know if the P85 would deliver a similar experience or would I need to jump up to the P85D? Thanks in advance!
