Re the "leather dash" issue raised above - the factory price list has an extra charge for a painted dash, or an option of a walnut dash - from that I assumed that a leather dash (or vinyl if trimmed in vinyl) is standard, rather than an option.
Would be interested to know - for future reference!
It seems to be one of those items that you can order, but is not in the price list. I have ordered a leather covered cowling for the steering column. It is not in the price list but can be ordered for a few extra £.
