- resale value (real or perceived)
- package pricing (Mercury Racing power, drive package)
- possible lack of knowledge of drive options
- local maintainability (probably perceived, Arneson hardly ever breaks)
There have been a reasonable number of Arneson Skaters, and we just recently had an Ilmor Indy drive 30 and a X-Power Drive 30.
For me personally, my next Skater build, will get serious consideration for Arneson drives.
