BMC is a top-shelf brand, and their Teammachine is one of my top-2 bikes ever ridden. The price is great, especially for the lighter and more expensive SLR01 variant, too. The only niggle is that it is a rim brake bike rather than disc. But on the plus side, this is the complete package and I see no reason to upgrade anything on it: carbon rims, carbon cockpit, etc.
However, make sure you test ride the bike before you buy it. The Teammachine has a more aggressive geometry — which isn’t bad, but you must be able to fit on it. Also, ask you bike shop to do a bike fit. That might add a fed $$, but this will be money well spent.
