Heh this looks interesting.. the ammount of times i've threw coffe all over my dads jeans from conering due to the really terrible cup holders is... well alot lol.
Assuming this looks well closed i'll do it, how about modding the exsisting cup colders ? I.e, drill through them to make the two holes through-and-through so you can fit your cups/coffers or w/e freely.. then when the glove compartment is in it's closed posistion , fit some sort of circle type grommet over them xD ?
