I did test drive a Gen 4 recently, but just on tar roads - I tried to hit as many imperfections (small potholes) in the road as possible, and it felt solid. If you press on the dash behind the instrument cluster, and behind the centre "speaker/grill", it does feel more flimsy than the Gen 3. But I didnlt notice any real rattles.
Is there anyone in the Cape, that has a Gen 4 and is willing to drive on some dirt roads with me?
Thanks,
Greg
