I'm not following Indy closely, but a few thoughts:

- Wheelbase: 123 inches. Is that number just marketing or is there any other reason?
- What am I to understand by "Mega-Line Assisted Gear Shift" ? It's the US, so sure it must be Mega, but what is it really?

I believe Mega-Line is the brand name, at least that's how I read it

Our gears are great, we have the best boxes, many people tell me that, real mega line gears.

No actually, it's a German company that makes the electronic gear shift system. So it's standardised.

Yes, Megaline co developed the gearshift mechanism with Xtrac to mate with the Xtrac gearbox.
