Being a student, I'm not the richest of people, and I currently use a P6 as a daily driver. But I have to disagree that £90 for a NOS or excellent wing is unreasonable. Compare NOS/heritage wings for Morris minors and MGB's and other more common classics... £220, £495 respectively. In which case, £90 for an excellent example seems to be a bit of a bargain for lets face it, a non essential part... It is possible to repair existing wings, or protect them from corrosion in the first place, both very cheaply and easily. But at the end of the day, what does it matter how the wing is? These are P6's, the strength is in the base unit, so unless you are doing a cheque-book resto, what's wrong with a bit of filler or fibreglass in the wings?
I do like the idea of cheap spares - who doesn't? Well, the people selling and storing those spares. Cheap spares appear to attract idiots. When it comes to advertising, it's usually a clear out - 'must be gone by the end of the week or going to the tip' 'oh I'll have it' - don't hear from them ever after, or they string you along for weeks on end and then cancel.
I'm currently keeping a carpet set for someone who won them and paid for them 99p on ebay, but are yet to collect them - we half arranged collection which stalled on their part and I haven't heard since. I guess 99p is too easy to throw away for the sake of laziness. People even offer parts free, though most people assume free means rubbish - I have been the only person to respond to quite a few freebies over time, that are perfectly usable with little work, yet would have been scrapped otherwise. If parts are going to stay at this stupidly cheap price, no one will re-manufacture them, and no one will keep them.
On another note, which is completely in keeping with the topic; I came under fire about a discussion of the prices of brake parts a few months ago. If you look at the prices of MGB brakes, It appears you can refurbish the whole system for around £400. The same parts come to double for the P6, which I think is too expensive. People were telling me that you shouldn't put a price on safety, as though my opinion on this matter is wrong. I think that for such an important part of the safety system, people running these cars should be able to keep the brakes in top condition, so the high prices of brakes need to come down, without a drop in quality... (profit margin vs customer safety and all that) This will act as an incentive for people on tighter budgets to fix brakes when needed, rather than continuing to drive about until they can afford to fix the rear brakes - I know it's been done, I've seen it! It will also help save a few cars; when I've helped people look at projects, one of the prospects that has put them off has been brakes needing replacement - they've then consigned the cars to scrap as a result. I shall go on to say I realise these parts can be rebuilt at home easily, cutting costs significantly, but there are people out there who don't or don't have the confidence.
As a conclusion of my discussion; I think that prices of important things like brakes should come down considerably, and the prices of things like wings should go up. I feel this topic has the priorities wrong. Lets face it, what's more important - Being able to stop in a straight line, or having a car that looks pretty?
That's my view, for what it's worth.
