Mazda 626 … which engine?

Hello. We are looking for a 626, because it seems to us for our budget (up to 2500 euros) as a good option, if you want to drive reliable still 2-3 years. A Nissan Primera Traveller would also be conceivable, but from the Mazda 626 one hears almost only good. Only certain Mazdas come into question for us, i.e. the years 1996 to 2001. Which engine is the most reliable here? We are not a flicker, have only two children and if we travel, we do not want to at least with a äch zenden engine on the highway crawling. So prefer 116 hp or 131 hp at 626? Not always the stronger engine has to be better. Thank you!!
