Ah ganon pala... No problem ba talaga ang fuel costs? Consider that most of the cars here drink at a rate of 3km/L thereabouts, especially those with 5000cc and above engine displacement. Kung nagka-XP na rin siya dati eh di siguro maiba na rin naman. Kung yung SWB XP ang hinahanap mo, the previous gen Suburban makes more power with slightly lesser displacement. But I suggest you give the Tahoe a second look. Mas malapit ito sa XP in terms of size. Haba ng Suburban eh.
