Started with this:
a red 1996 porsche 924s that a buddy of mine owns. He invited me to do join his endurance racing team. 24 hour long road races.
Then we got this dragon, a 1995 porsche 944 enduro racer. just to have a backup in the stable.
Finally I bought this true race car. totally track prepped 944 turbo pushing near 400hp used for nasa racing.
And I still take my m3 out every now and then too
Needless to say I've been spending a lot of weekends at the track. its a completely addictive experience.
