All large SUVs, and indeed large luxury saloons, are relatively expensive to run, and the BMW X7 is no different. It runs on wide, costly tyres, insurance premiums won’t be cheap and, though BMW makes efficient engines, the X7 won’t be as frugal as the smaller cars in its range. Nonetheless, the X7 is one of the most economical options in the sector and strong resale values will offset some of that upfront price. Buyers in this sector are unlikely to be put off by the cost of running a car of this nature but, for simplicity’s sake, BMW’s three-year, pay monthly all-in servicing takes stress out of ownership and includes two full services, fluid top-ups, a wash and vacuum every time you visit, map updates for the sat-nav and seasonal health checks. It also includes the first MoT.
