Is it possible to buy a new chassis for the 90 without having to get the galvanised one. I have had my 90 for 18 years and it was far from new when I bought it but has now failed the test badly with the chassis. If need be I would buy the galvanised one but I am hearing all petrol an diesel vehicles will soon be taken of the roads so I don,t want to pay a lot of money and then not be allowed to use it.
