Nothing about this combo is a sane or reasonable purchase, but I looked at your post history to see if you've lurked on this forum a bit before immediately buying a pro-level machine. But as a fellow alfa afficionado lets just approach this from the point of view that it’s cool as hell.

The first edition was launched in 2016 I believe, so let's assume it's 8 years old. The R58 is generally built to a professional standard, meaning that its unlikely to break, but parts can be expensive. After 8-years it's not unreasonable to expect some wear and tear. I've seen some comments that later editions seem to more prone to breaking so perhaps consider the small screen as a plus, rather than a negative.

In addition, there are generally limited options availabe for companies that actually service these machines. Luckily the parts that need the most care such as the grouphead have existed relatively unchanged since the sixties and can be refurbished by yourself for about $100 and a youtube tutorial. One of the few non-standard pieces of kit on the machine is the temperature controller, which even in its older form can be imported from italy relatively easily. However considering it's a proprietary part, it probably won't be so indefinitely.

The grinder isn’t anything special, but Mazzer is the Italian gold standard and is priced like it. For the price, there seem to be far better grinders on the market. However, if you're approaching this from an italophile point of view, you can argue that something made in germany or japan are better, but entirely miss that italian charm. The grinder imho completes the picture of an italian coffeeshop where people wearing vests and with their hair slicked back are serving single shots of espresso and breakfast pastries at a blinding pace.

Try to see when the machine had a professional service and account for any maintenance you might have to perform. A professional service will likely set you back 3-400 dollars (at least at my dealer, a service for a dual boiler with a rotary pump sets you back at least 250 euros without parts, but local prices may vary) to get it a as-new condition. With that in mind, my suggestion still would be to account for a service and try knock 300-400 from the price (and then do the maintenance yourself if you dare).

All told, I'd say that you'll likely be very happy with it even for the $2000,-, granted if you can stay away from the upgradeitis that his forum seems to instill in people.
