I find the Laguna comment interesting, a good few years back my old company stopped the VX only policy and let the reps choose any 'exec' car up to a price point. Two out of 10 chose Laguna because they had better spec to price ratio than the other options (including migs), one guy had a few problems including a new gearbox and diff. The other guy declared it the worst car he had ever drove, he had the box done twice, the diff done 3 times, numerous ancillaries replaced and the real kicker he had the equivalent of a blocked breather but it pushed the gas into the car. They only found the problem when it went in with dash problems and the mechanic happened to pick up on it, he had driven it like it for months without realising, it answered why he was getting huge frequent headaches.... At next renewal all Renaults had left the list.
And even so called top marques have problems, my daughter has a BMW made John Cooper Works Mini, 40k on it and the timing chain failed as did the entire entertainment system, luckily both under warranty as the system was a £3k replacement. It now has the same chain rattle again and BMW are trying to wriggle out of replacing it as it's only a 'little noise'.
