So with the expiration of my 2012 Volt's lease, GM's delay of the 2016 Volt introduction (in Texas) and Tesla's introduction of the CPO program I am considering picking up a CPO P85 or P85+ later this year. The primary delta for the P85+ seems to be around the suspension (bushing firmness, different sways and air bladders, etc.) and the staggered wheels. Obviously, I can't just go test drive a new P85+ vs. P85 since they are no longer available so I am looking for real life feedback on the ride quality and any "tire" challenges you have seen. In addition, I find that it is easy to overlook or gloss over something on a test drive which then becomes a pain to deal with every day. Although I am coming from a Volt, my previous ride was an '02 M5. I became a BMW fan when I realized just how they nailed the BALANCE between handling and ride quality (particularly in the E36 and E39, but I digress). The M5 "only" had 18" rims (staggered) however. I am also keenly aware when manufacturer's miss the mark. We purchased a Volvo XC60 in 2012 with the R-Design package. This included firmer springs/struts/shocks in addition to a host of other items. Unfortunately, I think Volvo simply got the rear shock tuning wrong...just too harsh for only a modest improvement in handling. 90 days post-purchase I crawled underneath and swapped in the base touring suspension rear spring and shocks. On my '05 GTO, the rebound was just way off and gave a bouncy ride...new Konis took care of that (first time I was ever impressed by an aftermarket suspension swap). The biggest variable of all (beyond your personal tolerance for a given ride) is how rough the roads are where you live and drive every day. I'm in the Dallas/Ft. Worth area as an aside. Anyway, two items: 1. How would you rate the ride quality in therms of impact harshness (i.e. edge of potholes, expansion cracks, etc.), shudder transmitted through the cabin, and general "getting tossed about" on your daily drives? 2. How is life with the staggered tires? In my own past experience it has been mixed. The M5 wore very evenly, but I've had other cars where they didn't and you just end up hosed w/o the ability to rotate...those cost to replace is, of course, another stinger. Thanks!
