Haven't driven a CX platform but Series 1 and 4's seem to be the best handling of the Aero series. 5's attrocious without modifications
What do you think is wrong with the 5 as I have not noticed it?
Nothing that a complete change of the suspension, ARB's, OEM Tyres, spring rates etc cant almost fix. Changed all of mine when it was new back in 2016 and it got it up to a 1990's Morgan standard :-). Perhaps on the tail end of production they may have made some changes that I'm not aware of but if you drive a Series 4 on a mixture of good and bad roads and then do the same route in the Series 5 and then see what you think.
