As for rattles being inevitable, how so?
Every car I've ever had rattled to some extent (and I've had a few). Worst offender was a new Peugeot 205 GTI 1.9 in 1986. Horrendous build quality

More recently, an Audi TT (2000) and Porsche Boxster (2000) - overall these weren't that bad though.
The GTi has proved rattle free for 12 months but now a couple have arrived in the past week - sunroof rotary control, dash centre air vent (both well known and easy fixes) and an upper drivers door rattle. Will fix these myself

My tyre pressures were too high following a service 2 weeks ago - ride was too harsh. Now adjusted, much better and ride is smoother and not so harsh on the car. Road surfaces today are pretty sh1te and this also impacts upon the cars ability to remain rattle free
