Good luck! Out of the million+ people in the UK who mod their car very very few ever get sponsored...
you could try offering your car as a demonstrator - mine was a spec-r demo car for their 206 range of engine styling, and I lent them my car for a couple months to help design the kit
oh ok, thanks very much, uuumm with regards to how you did it? did you have to pay anything, or did they just have your car to try out thier stuff? thanks for the advice tho.
