Hi Thomas, and welcome to the forum.

From what we can tell, the Modena was the Monza for the German market - most of them we have seen have still been in Germany. If you search for Modena here, you'll find what few entries there are.

So, a rare watch but not one that's fundamentally different from the less rare Monza, so the price would depend on how much of a premium any buyer is willing to pay for that extra degree of rarity. From my view, a 5,-k € offer is quite a generous one, but for me Modena is a bit less evocative than Monza - Maranello might be slightly different, but I'd probably still opt for the race track in the end.
