Currently looking to pick up and Ep3 CTR for use at weekends etc. Ive seen an 03 plate with 96k miles. Has a full stamped service history and looks to have been looked after. Im wondering what the timing chain replacement interval is? Dealer says there is no evidence that it has been changed but has main dealer history. Has put me off slightly if it hasnt been done. Am i right to be put off or am i being ott?
