I just bought a xg350L, 2005. Yes I bought it used, when I first went and took it for a test drive it acted like it was missing. Eventually the check engine light came on, the dealer had it taken into their shop, ran the computer on it. filled it with premium gas and the problem stopped. no more surging... so that means this car wont run with ordinary gas, it needs plus or premium... no problem there. we have driven it for 520 miles now, excellent ride, comfort and dependable. I love this car
