[Mr Payne]

reliability: Japan, US, European
staight line performance: US, European, Japan (if modded, tie between the US & Japan)
track usability: I'd say Japan, US, then Europe. Don't really know though...
looks: All have ugly & good looking cars.
prestige: Different things for different people.
*engineering*: Manufacturing engineering? US or Japan.
Actual "mechanical, aerospace, & chemical" engineering? I'd say Europe simply looking at where F1 companies are based.
