(New edit - I decided to read a bit and learned a bit)
Ok, I just got done reading the terrific post that KennyG put up regarding his recommendations based on shooting Druids at Outlon Park. I'll try shooting at 1/320 in AI Servo mode the next time out. Still looking for lens recommendations for my budget.

Hi all, new to this forum.
I've been shooting auto racing events for the past 4 years. I primarily shoot vintage road racing and hill climb events. I would like to improve the quality of my images where cars are coming towards me. My image quality has been a bit hit & miss, with some serious focus issues.
I have a Canon 40D, and am looking for a new telephoto or zoom telephoto lens, but don't have an unlimited budget. I have rented several lenses, both high end and mid-range, with mixed results. My guess is that I have a technique problem more than a hardware problem.
In most cases cars will be approaching between 60-100mph. At this speed range I'm fairly sure a shutter speed of 600-800 should be acceptable to capture the primary point of aim sharply (correct me if I'm off base here). With the cars taking different lines and considering unpredictability of racing in general, I don't want to lock myself into a prefocus point and shoot in manual mode. Should I be using AI Focus or AI Servo mode? Are there any tricks regarding where to set your focus point for best results?
Lastly, with a budget of $1200 or less, what lens would you recommend?
