I own a '91 318is and a supercharged '98 M3 Sedan. Benn invloved with BMWs since 1998 when I bought a 1.9L Z3. Since then I have owned and tracked almost every BMW Ive owned - Techno '98 M3 Coupe, '99 Z3 M Coupe, the Z3. 97% of all car work I do myself.
Out of all the cars Ive drievn on track, the z3 and the 318 have had the most modifications and been the most satisfying to drive fast. Ive driven at Lime Rock, Summit Point and Watkins Glen, but most of my seat time is at the Glen.
Below links to two track videos, edited to provide more visual entertainment.
First Watkins Glen 1.
Many years before Saab used Paul Oakenfolds Ready, Steady, Go in their lame ass commercials, I used it in my own driving video with much better impact.
