Hello, I am interested in your opinion regarding 6-cylinder engines of the 90s… so V6 (c25xe,x25xe) in vectra or calibra against e.g. VR6 golf3, corrado or passat – or what do you think… which 6zyl. was really good at this time? bmw r6 2,0/2,5? benz r6 2,8/3,0? …usw… am curious about your opinions…
