Thanks Dave. Have found Liverpool Chrysler. it's part of Lookers now on Sefton Street. I mentioned your case to the warranty man at Hatfields and he Thinks it should be ok. Mine is the roadster too. Shocking on a 4 year old car! Just had brake pads and headlight bulb all in the same week. Am not a happy bunny as far as cars go this week lol! I'll let you know how I get on with the corrosion.
