Which car parts are cheaper? Audi, Mercedes, Volvo, Saab or BMW?

Neither, they're all expensive. If you got connections in Europe then you shouldn't worry about prices.

Honestly I would say Saab, next to that Volvo then the prices get higher when including Audi then BMW and then of the highest price, Mercedes.

1. Mercedes

2. BMW/ Audi Tie

3. Volvo (owned by US thenn sold to China)

4. Saab

saab is probably the cheapest. Mercedes is definitely the most expensive.

I would expect Audi to be cheaper than BMW.

not sure about volvo.

What about VW / Audi? They are cheaper to buy, cheaper to fix, cheaper to run. What about US Domestic? Asian? Also, BMW and Mercedes are very uncomfortable to sit in for long periods (like sitting on a cinder-block) Of your non-choices Volvo's have the best dealer/warranty support.

Probably Saab, mainly because a lot of parts have GM origins, but also because Saabs aren't really good cars. We've been tricked into thinking that they are proper luxury/sports cars. Although that might change now that Saab is owned by Koenigsegg.

depends on where you buy them/audi is only audi/saab is only saab/the rest can be gotten from outside sources cheaper
