Got agree as well. Ran a manual for 26yrs. Switched to a C4 last year and won't look back. Much easier to setup the suspension for an auto as well. When you start making good power manuals become just too violent, well at least in my case. My brother owns a blown 98 cobra and will be making the switch from his TKO500 to a C4 as well.
