Everything creaks and rattles, the windows squeak when you roll them with any sort of moisture present, the speaker bass farts and rattles the interior, there is noise from inside the front axel that requires periodic maintenance (look it up on Tesla forums), etc. etc. No comparison to Mercedes, for example.

But the drive is amazing, so in the end, it's all worth it. Tesla should really concentrate on the interior because it nailed the drive itself.
