One further factor is the older combi's can run on softened water in the heating circuit where newer models need to be fed standard hard water (doesn't affect soft water areas) so either you need to bypass the softener while topping the heating circuit or use the direct feed most softeners are provided with and plumb heating feed into that.

New boilers will(should) have some form of manufacturers cover and getting extra cover should be cheaper than covering an older boiler. We want to try to keep our old unit (still running at A rate efficiency) while we can for the above paragraph reasons as well as not spending thousands we don't need to yet.
