Easy once you chosen a car don’t look at the ap of other cars you might of liked or are just out.
Often new cars have some sort of issues at 1st (when they released) and a lot these days are software related and look imo car makers ain’t so good at writing code and adding what if’s to it… so the sys don’t crash all the time.
The more we go down the route we going the more issues i see.. fly by wire brakes etc that got no phyisical connection is one, over the method we have now and has worked for a long time. Like with no wing mirrors now they cameras. if there a glitch what then. look you can get a mechanical error but i dunno if a sensor or the system crashes what then no brakes as no connection. Signal is lost then what no connection..
but as for feeling bad as long as you let them know well before handover and you arrange to collect, should be no issue at all.. Personally i have not cancelled one car i have ordered on the scheme. but it’s when people do it afetr they registered the car or ordered it in a colour of with extras no one really want’s.. I can see there being any issue in doing so. I could of cancelled my newest car because of the covid, but so glad i didn’t am loving it..
