Hi, Ive got myself a 2001 Lexus LS430 and the cover for the headlight washer alongside the components beneath flew off, was just wondering if anybody knows a good place for parts or for a replacement please let me know. Its a tiny part and Lexus quotes £300 supplied and fitted, any garages or trusted places who could do it for less would very much be appreciated, if you need pictures just ask
