does anyone know where there is a Toyota import spares dealer in the Uk?

I have aToyota Lucidia and have just had to replace part of the immision system it took my local garage three days to find spares and then it was from a dealer who said the bits he had were off another car that would fit. I would like information about spare that are correct for my model of car. Thanks
