roll bar types

[diverrick]

I have been looking closely at SPF cars recently, but they always have the single or double individual roll bars installed.

This week I find, not one, but two with full width roll bars. They have a bar that runs forward from the roll bar inboard past the passenger seat.
I had not seen that before and wondered of that was an option,or maybe an older version? Good or bad? Standard or non standard.
Looks like it would be a real solid roll bar, in the event you ever really needed it, but then again, it looked like the passenger would be constantly hitting their knees against the bar that runs forward.
Does this make the car less valuable?
I have noted in my search for a car that the ones with automatics sell for less than the ones with manual transmissions, so I was wondering if the roll bar style also impacts the price.
