Hi,
First post on these forums after lurking for a while.
It would be hard to single out a particular year as favourite but I think 1991 would be a good bet. 1989 to 1996 was my favourite era simply for the fantastic looking cars and amazing V10s and V12s. I'd never miss a race back then and absolutley loved F1. Then they ruined the cars, the old school drivers left one by one, F1 moved to ITV and they got rid of Murray Walker. It just wasn't the same to me after that.
This year is the first season I've watched every race in a long time. It's been a lot less predictable than recent years and at least they've brought slicks back. I'm actually starting to like the look of the 2009 cars too.
