I'm afraid I'm new here. What silly 32/42 debate?
Essentially, there are pros and cons of both, and their respective owners will of course support the one they have.
As a started [3200 vs 4200]
When the turbos kick in they are a bit mental vs. more linear power curve (though on road performance is similar with them both)
Boomerang LED rear lights vs the Honda prelude look.
Bonnet vents vs added bulge (plus more visual things if you look at face lift 4200 or GranSport)
Less reliable vs more reliable.
Traditional Maserati style twin turbos vs Ferrari developed NA.
Better manual box vs porridge stirrer or normal auto vs more involved Cambiocorsa.
Build and interior quality improves with the 4200 too.
Personally, I have a face lift Honda Prelude with a porridge stirrer, and I love it.
