LMP:
Dyson Lola Mazda x 2
Drayson Lola Judd
Cytosport Porsche RS Spyder
Intersport Lola AER
Autocon Lola AER/Judd??
Highcroft Acura ARX-02A
Peugeot 908 x 2 (Sebring & PLM)
possibilities & dreamers for LMP:
Audi R15 x 2 (Sebring & PLM)
de Ferran ??
a second Highcroft (Lola Aston

)
Corsa Ginetta Zytek GZ09SH
Creation Judd
Mundill Pescarolo Judd
Eco Radical SR9 Nissan
GT:
Porsche:

Vici
Ferrari:
Extreme Speed x 2
Risi
BMW:

Robertson Doran Ford

LMPC:
