welcum, oops willkommen. i happen to own all 4 makes of various models in my lifetime, thus it’s from my sexperience. and since i’m also a diy guy, i spend considerable amount of time with various autos in the garage and my friend’s commercial auto garage which is also a body shop. drivers’ perception and sexperience in sillycon valley rate the new audi models over mercedes and bmw equivalents in terms of prestige (price over value) as most audi models purchased in the valley are in the larger and luxury range (2.5l and up), not the smaller and diesel “commute” audis sold in germany. for sexample, the 2020 audi a6 average price is $56.9k (msrp $59.8k) while the 2020 bmw 530i sells for an average of $50k (msrp $53.9k) and the 2020 mercedes c300 sells for an average $37.3k (msrp $41.4k). the 2020 mercedes e350 rwd sells for an average $48.3k (msrp $54). in terms of msrp, mercedes e350 equivalent of bmw 530i is a grand higher but when sold it’s about $5-6k lower. thus, in prestige rating, bmw is creeping into mercedes’ territory. in sillycon valley, the higher the price, the higher the prestige. the wealthy don’t care much about reliability. they change auto models almost every other year.
