UPDATE -Does anyone know this 4.6is? No clean title :(

[AV8R4AA]

I test drive the X5 again today.
A couple of 4.6 questions.

1) Does the tachometer yellow and red light stay on after warm up?
2) does the M62 coolant tank have a lollipop floating dipstick?
3) one of the rear heated seats was odd. The switch worked, but the 2 lights went out
within a minute or so. What's that mean?
4) This X5 has a much easier to turn the steering wheel.
My 4.4 is heavy on the wheel, comparably.
5). This X5 has the sliding cargo tray, do they work? Rattle a little bit?

Thank you Guys.
