Insurance group~ same as all other R32's although some companies will load the policy differently if they know what the hell they're on about.
Power? (told around 150hp)~+5hp lol, tbh tho it's a daily so why worry about that.
Price? ~ like anything all down to condition, but availability is the issue as R32's seem to be getting rare lately.
Mpg? ~ an honest 25mpg for me that's doing mainly short journeys to work in the week
LSD?~ nope. weld it, also some have s13 rear frames which is a plus for skids.
all based on last 3 years of ownership of my 2 door, I would also point out it drifts fine despite what people will tell you and the engine loves some abuse.
