They are certainly a different breed, I agree. I started watching F1 in 1980 at the age of 5, slicks were all I knew. I love the earlier machines, but to me, modern F1 is slicks. I still think the cars of this new century are the ugliest, with their high noses. I just hope this signals a return to mechanical grip, and a reduction in aerodynamic grip. With no traction control and a proposed return to manual gearboxes, I think the racing could get quite interesting.
Mind you, the finest F1 machines predate F1, I love the old GP machines of the 20's and 30's. Maybe it's just me, but a Bugatti T35 can keep me captivated for hours. I went to the Canadian Automotive Museum on the weekend, and they had a black T37. Just gorgeous. Everytime I run into one of these cars, I can't tear myself away.
