Rather good, pleasant location, composition is sound (although I'd clone / crop that piece of white on the bottom edge of the image), just a pity there isn't too much exhaust, although you don't tend to get too much in summer unless the engine is working hard on the mainline.
I've never used AutoHDR, but I'm hugely relieved it's not overcooked it to within an inch of its life. This is as HDR should be done.
