The ironman edition doesn't differ from the rest of the others VX's.
But the reason there's an ironman VX edition is because isuzu sponsored the famous triathlon back in the 90's that was named so.
The logos on the hood insert,the recaro seats,the rear fenders & floor matts makes all the difference,but this edition was the most expensive of all VX's
Nuh UH!!! It was named after ME!!!! IAMIRONMAN!!! DUN DUN DUNDUNDUN DANANANANA NA-NA-NAAAAA....
We sit together, my VX and I, until only the VX remains.
I'm just guessing, but perhaps that VX has an aftermarket air filter - rumor has it they make a louder sucking sound when there is more air moving through.
I second that! I have a K&N that makes a pretty harsh sucking sound, but with my custom exhaust it just sounds right.
Cars designed by spreadsheets make sense. Cars designed by engineers make history.
