I think you made a excellent choice for a flashlight to keep in the car, its robust and and takes AA’s so you can just leave it there without worry of monitoring lithium batteries often.
It was one of my first reviews (HERE) and probably the light that switched me to AA and AAA only lights as I started selling off all my 18650 lights shortly after buying the XP-G version. After that I bought about half a dozen or so XR-E ones from DX to give to friends and family.
Shiningbeam also has the XP-G2 version for $16.75 for USA customers but it works out about $25 shipped to Australia.
