Wise words David.
Yes, my last 156 was somewhat hungry when it came to wishbones, it was only the uppers though, the bottom ones were never replaced, and I sold it at 72,000 miles.
In that time, it had gone through quite a few uppers. The handling would become vague after about 10,000 miles on a set, and then the squeaking would start to drive me insane. I think it was due to me driving 'enthusiastically' on bumpy A roads every day. This would also explain the number of sets of Goodyear Eagle F1's I went through.
Of course, now that I do the same journey in a Brera S, I'll just need to pop into the Osteopath every 10,000 miles instead, which will probably work out at a similar expense.
