Never driven one myself, but have read many reviews that shared a similar experience to what Speedy! had.
I'd try to rent one for at least a few days & see if it's what you really want. For me, even tho I love 'motor music', in some vehicles it gets to be too much & becomes irritating after a while. Add to that the intrinsic nosiness in the cabin & harsh ride and, well .................
The other thing is the (annoying AF) MDS on the 392

. It doesn't seem to bother some, but I came to hate it in the short time I had the DDSRT. Again, you need to experience it for a bit to see if it's intrusive given your driving habits & speed limits on local roads etc.
