Well my car is owned by Alfa/ Fiat.
It was serviced at 12 months and 12K (because thats what the sticker on the window said), so at 24 months I got letterd by the dealer, but when I tried to book it in, was told I wouldnt need one till 30K (18K/24months now sir)
Anyway, it recently goes in for a repair, I am then told its missed a service and they do a service at 25K, 14 months after the last one??????
This is their money, not mine, so this is far from completely clear and I think people may still get gip with teh warranty if theyre not careful.
