Building a Car from Engine to Completion

I don't really know what you mean, multiple of what sort of options?

I mean you can't choose both DOHC and OHV for example.. what sort of multiple options are you talking about?

What about an OHC for the intake and pushrod for the exhaust cam?

Somewhere, somehow, an american will have done that...

Killrob: Loady, copying wikipedia articles doesn't help anyone, I put the link here instead. Please refrain from posting in that way in the future.

For driving assist and those kind of options.

Under driver assists, say I want power steering, but I also want traction control. Will I be able to select both?

Oh, well if that's the case... Kind of.

In each list you can only select one thing, with each item superceding the one below (or including the items below), this is something we need to work on to make a bit more clear
