Should a chain cam on a Corsa need changing?

On a car of this age with such low mileage it's would be better to concentrate on corrosion damage limitation tactics as I am assuming you want to get the longest possible life out of the vehicle. If the body is still sound, and Corsas tend to be ok on this, then you should consider waxoyling it. You could do this yourself as the kits are widely available and I can vouch for the effectiveness of such a treatment. On the mechanical side, with such low mileage and use, you should have minimal worries.
Thanks for the advice.
On a different but related matter I drive a Vectra SXi which I bought recently with 35,000 miles on the clock. Again I enquired about the cambelt prior to buying and was told it was a chain-cam that needed to be changed a 60,000 miles. Are things different for Vectras and chains?
Waxoyling? Do Halford's have such kits?
PS I thought that I better qualify my statement 'A chain will not break'. If the timing chain becomes noisy on either vehicle then you must have it changed as it CAN break but you will have plenty of warning - unlike the belt drive which is a 'silent killer' LOL. Premature timing chain wear is generally caused by poor servicing. A worn chain will produce a rattling noise on tickover which disappears when the engine is revs are increased. Use good quality oil and filters and relax in the knowledge that it is unlikely for you to have problems and if you do you will have plenty of warning to prevent catastrophic damage. You seem to be a careful owner - most people I know don't even know they have a timing belt or chain !!
Everything was repaired free of charge but the car was never the same and I had to top it up with oil every week. I managed 140,000 miles in it all told but the incident taught me to be careful.
