Congrats! and all the best, Stefano.
I was married to a Peruana, she was from Arequipa, but had relatives in Lima,
so I have been fortunate to visit many parts of Peru...
The family is SO important, there, if she has some there, I hope you will visit from time to time. You'll love it, and there is so much to see, wherever you go, Huaraz is "little Switerland", don't miss Caraz and around, the Gold Museum in Monterrico, Lima, see the Pres. Palace,stay inMirafloresneighborhood (Their Beverly Hills, the Mercedes dlr is there, it's near the Panamerica Hwy), the Jockey Club Shopping Center in Lima is a must see, Arequipa is a treasure, see a bullfight if you can, (hey are unique in AQP)theSta. Catalina monastery is like 1 block from the city square yet like going back to 14th cent. Spain) take a trip to Cusco, see the old city and a day trip to Macchu Picchu, and perhaps the churches of Ayacucho, or a helicopter ride over the Nazca lines (near the coast).
You'll love the Peruvian food, from papa a la Hauancaya to anticuchos, their food is like no others, and yoou can get loaded on Pisco Sours when you're out.
I did visit the Mercedes dealer in Peru, there's only one, it was called Automotriz de Peru SA (now called Divemotor SA) and got the coolest dealer sticker for the car (which it still has) the funny thing was I got the sticker *before* I bought the car!! Not very many Mercedes in Peru, but there are some around if you look, from beat up fintails to newish C43. Even a few S class, and I saw a nice 250C coupe in Arequipa once. The everyday cars are mostly Korean and japanese. I took a coastal ride to see the nazca lines in a '66 Cutlass with a nissan diesel engine.
When you shop, get a nice alpaca blanket shawl or blanket. If you went to the markets, you'd have to decide whether it was alpaca or baby alpaca, handmade or machine woven. Your wife probably help, and the # 1 store for the best Alpaca goods is called "Alpaca 111", they are in Lima & Arequipa.
You can commission jewelry made in the better areas, and it's cheap for real gold! Idea for Lima and Arequipa shopping, order it and pick up in a few days. Finest upscale jewelry in Lima is at H. Stern, they are an Intl. outfit.
It's a lovely place, there are some beautiful pictures posted in the Peruvian section of
