Nothing wrong with a facelift XI, gas mileage is just fine and pulling off from a dead stop in deep snow or icy conditions all the time doesnt hurt either
When I had my 325 rwd obviously each stop was ar roll just to keep momentum at most stops lol
Around town driving I see 500-550 km to a tank and highway run to quebec this year past got 700+ out of a tank before I decided to pull off and eat/gas. Not incredible numbers but decent.
XI's will after 80000-120000+ km decide to cost you front boot(s) and shafts though, only extra cost I can see so far and every week at the shop with our routine customer xi owners. Same thing on the odd X5's but the dealer parts costs are a major rip off so shop it around, or call Eurostyle!
