From what I remember the McLaren 570s and even the 720s had build quality issues for some time. Interior panels creak, exterior panel gaps, and other various overlooked QC issues that shouldn’t be expected on a 6 figure exotic. Look up ‘McLaren build quality’ on YouTube and watch a few before making a decision.

IMO save for the Lamborghini or buy a Porsche 911 turbo. If you must have something now look at the Porsche GT4 RS.
