Are there any flaws or special features to consider when buying an Omega? I want to get the Omega Caravan with the 115 HP motorization. Built 12/96, 135,000 km, timing belts, brakes all around, wapu and track rod heads were made last year or this year. How are the timing belt changing intervals with this motor? I know that from my Calibra 8V, there were 100000 km, but I think that in the Omega B there is no longer the C20NE engine, right?
