My battery (Yuasa) just packed up so went to Lexus Birmingham to get a replacement, 106 quid , it was only 25 pounds dearer than the Yuasa...not too bad.
I asked them to give me a quote on Cambelt,w/pump ,all the pulleys and a new tensioner , the lady there didn't know as it wasn't part of their fixed price service so promised to check with service dept and ring back which she Didnt.
