Everybody's experience is different. There are several who have said that on their first day out, they were leaving 911's and Corvettes in their dust with their 968's, prompting people to ask them if they have a V8 or a turbo (or both?!) under the hood. Me? For several sessions, I was by far the slowest car out there. Cars were passing me in parades of five at a time. I was absolutely horrendously slow, even though to me, I felt like I was driving like a maniac. After that first humbling session, I was so thrilled to pass a Suburban carrying a family of about 8 on the freeway onramp that I was practically giddy. And even after getting several sessions under my belt, I was finding that, among other things, I was spinning out at astonishingly slow speeds.
But as I said, I just stuck with, and ended up enrolling in a local driving academy, which allowed me to get to the track at least once a week. Slowly, things started to click, to the point where I became one of the faster drivers out there, where suddenly
I was starting to pass things like Corvettes and supercharged Nissan Z's. So, as long as yo enjoy the driving experience, try to get out there as often as your budget will allow, and it's true what they say - the speed will come.
