Pricing “teurer” cars

Hello, in some threads it was said by some participants that one can expect “this or that” at a certain price. I would like to take up this topic with you. However, I find it difficult to get started because we would have to group a lot of things. What would be price classes? What would be perceived as “high quality”? I get this: – here in the forum it is said that one has to expect for “round” 60,000 euros for an XC90 V8, i.e. 10,000 euros more than for an XC90 T6, “more” than just a larger engine. My counterthesis: the larger the car, the less you get as a countervalue for it, but you buy prestige. Best example: BMW x5. Was there in 2003 a 4.6is for 78,200 euros, which has just 27hp more than the 4.4i for 62,700. (good of the 4.4 needs the sprot package, the met-lace, i.e. real price difference: 12,000 euros) Or differently: how much cheaper must a VOL be equipped as a comparable Audi/BM or VOL for a better version of the Audi/M
