Beautiful colour: I miss it and my hairs tingle when I pass one in the road because I really loved my last bakkie. Not to say I don't love my current white one just as much.
What made Thunder special, was that it was discontinued in late 2014, making those of us who owned one have a bit of special edition status. Mine got me above book trade because there is used demand for the colour amongst certain buyers...
Re the camera and PDC: I don't know how my brother lives with his XLS supercab which has neither. I find both features equally valuable. The PDC is useful for catching missed objects on the sides, while the PRO thing about the camera is that you can zoom right in on the towball when performing a parallel parking manoeuvre. It means I can stop 10mm from the bumper of the car behind and then full lock forward to get into the bay cleanly. Love it and it scares the CR@P out of people sitting in their cars. So many have blasted the hooter in a panic as they thought I was going to hit them.
XLT pack should give you both if you are buying an XLS.
