@RJB Thanks, it's great to share the experience of 410 ownership to some extent through reading your posts. Pictures are always appreciated too
I'm intrigued to hear your thoughts on whether the charges to the 410 over the 400 have compromised it at all as a pure road car. My 400 is my daily and I suppose that some would consider this compromised when compared to a hatch or SUV, but I am more than happy living without multiple cupholders or the ability to put my dogs in the boot (I suppose I could still technically do this but it's not advisable) for what I get in return. If the 410 offered additional dynamic improvement and a greater feeling of 'specialness' I'd be happy to live with more NVH or a harsher ride.
I have little or no interest in taking my car on track, so if that's the only place that the improvements are felt then the 410 is probably not for me.
