Hello, it is hard to decide between the Mercedes and Ferrari for a favorite. Mercedes has been in my life since 1971 when dad bought his first. Their technology and innovation has always impressed me. But red is my favorite color and who can't like Ferrari? Perhaps with Alonso, Ferrari will again have a driver with heart, desire and ability to win a driver's championship for them. All the GPLs are nice though, my track is Monza from '55-'69 so these cars fit my era perfectly.
For driving, I remotored and regeared the early cars with the newer motors and 9-25 gears. So no one car gives significantly faster lap times than the others. The parity provides good racing when I have to provide cars for races. Hopefully the experience of driving the GPLs will create new converts.
Trust me, your English is much better than my Spanish.
