The problem with Vectra's isn't so much the car, yes they feel cheap inside compared to VAGs but hey, they were only £27k new so what do you expect. 
But it's more the amount of common faults with them - snapped springs, stuck EGRs, broken swirl flaps, DMF, squeaky aux belt, rad mounts, 3rd injector wiring, thermostats...and the list goes on. They're plenty cheap enough as below, but they're really no more reliable than a 306!
