My advice is don't go looking for problems that in all probability aren't there. Contributors on here have at times worked themselves into hyperbolic / apoplectic rage over issues which in at least one case have required a good portion of humble pie with the dealer / manufacturer. Many of the gripes and moans on here are just that, and the faults which can seem to be so prelavent based on a narrow focus and fairly voiciferous minority, are not experienced by all. Your dealer will do a PDI, just enjoy the car, and be reassured that you have a fairly comprehensive warranty plus consumer law should they have not done the PDI professionally or should something go wrong.
Yes it is a substantial investment, yes you have expectations of quality standards (it lives up to mine) but it is just a car, and a mass produced one at that . . . Glass half full folks.
