As a Merc diesel owner I was contacted by one of the ambulance chaser companies, they wanted claimants to make a statement that they wouldn’t have bought the car if they’d known at the time. That’s simply not true in my case nor for most I suspect. Some will no doubt look upon it as an opportunity to get something for nothing. The problem is that these claims must work else these companies wouldn’t spend so much trying to get claimants, think how many “miss sold PPI?” calls you had. At the time of the VW “scandal” I was convinced that there’d be more to follow but I didn’t think it would take so long.
