I have a slight creak when turning left into a junction whilst the motor is braking. There's a TSB for a similar noise which recommends changing the gearbox mount. They changed mine, which seems to have made a small difference, but it's still there.
I also get a very quiet thud (thud makes it sound like it's loud...it's not but that's the type of noise) when slowing to a stop under full regen. If I lift off at say 30MPH and let the car come to a full stop, just as it stops, it makes this thud as though something is dropping back into position. Looking at the gap at the back of the upper motor mount, I'm guessing it is indeed the motor dropping back. They're going to check the motor mounts next time it's in, but I think it's probably normal.
I think the biggest "issue" with the SE is that, it's so quiet, you can hear every noise.
Edit: As for tyres...I fully expect the SE to chew through them because of the instant torque delivery.
