I came from a MIA 2020 LR with acceleration boost, to a MIC 2021 P.
The ride is a little firmer, but more planted. I genuinely can’t tell any difference in road noise, I find both acceptable and neither intrusive - no problem holding a conversation on the blower @ 70.
I reckon I can feel the difference in acceleration from the line, but not really once rolling - both models are…. Adequate
Quality, meh! I had a pretty good MIA, the MIC does feel better inside, but that could be the modified interior design. The panel gaps on the P are as good as any other car I’ve had, as is the paint quality (to the untrained eye).
I prefer the look of the P.
Confirmation bias? Probably. Are all these things subjective? Definitely. Was it worth the extra $? For me yes!
What matters here is that you are happy with your decision, and you will be
