Actually, the reason I asked the question in the first post in the thread was because I was looking at a Yanmar-equipped Pearson 30 and an A4-equipped ODay 27. The ODay was $2k cheaper, but clearly the P30 was the better buy as it was the bigger boat with a diesel. So you are right that precise comparisons are not possible, but it is possible to make rough comparisons that are helpful.
You rarely see boats on the used boat
market with "newly rebuilt" engines of any kind. Most likely sellers figure that buyers would rather have the choice of rebuilding or repowering, but I'm not sure that's a wise selling strategy especially in this market. It seems that boats with any kind of significant issue, like a bad engine, are very difficult to sell and usually end up going for ridiculously low prices.
