door mirror glass which type after market reversing cameras/ parking sensors

[lotusesprit1]

Finally got my esprit back on the road since before the covid lock down.

Reversing it back into the slightly narrower garage I spotted one reason why its so awkward to reverse using the mirrors my door mirror have different magnifications! having looked I can get concave or flat relatively easily  which are best /originally fitted?

Any recommendations for an aftermarket reversing camera the eBay one I have works but has a narrow viewing angle and takes ages to stabilize.

would it be sacrilege to drill the bumper for ultrasonic sensors? I have matching midlife crisis red paint....

get both, see which is better. - so long as they are not mega bucks.

I very much prefer the flat glass, as it doesn't deform or magnify.

Most parking sensors, especially aftermarket ones, are useless in my opinion, as they give a constant beep when there is still some margin. I can drive that close without aids, a camera can help to get just that little bit closer still.
