Buying tip Facelift yes / no

Hello guys, I am playing with the idea of purchasing an Omega Built 98 – 00. It should be an automatic transmission, like with V6 (I think the four-cylinders have with automatic too little steam) I have read here about the problems of the 2.5 respectively 3.0 L engines with timing belts or crackers. Of the latent existing drunkenness of the 2.6 and 3.2 L engines also. I tend to actually a MV6 Built 98 / 99 with approx. 100T-120T Km. Shouldn’t cost more than 9000 Euros. Or rather model year ’00 for 2000 tacken more? My question to the (un-) biased forum participants: What would you recommend? Are the motors of the facelift models more stable or you just don’t know that yet? Thank you from the snowy north cometino
