Poor quality at 11 months old C30 Strong rust infestation!!!

Hello, in the last 4 years 5 Volvos bought, last year a C30 1.8 F and a V70 2.4D. I have now changed the winter tires at our C30 itself and after 11 months and approx. 8,000 km of driving performance a shock, in terms of the quality of the vehicle. If you make the trouble and the wheels unscrew, you can see on chassis parts, drive shafts screws, shock absorbers etc. massive rust! I am not talking about flight rust, but real base metal corrosion. To my astonishment I then on the same day still on my 4 month old V70 with almost 25,000 km on the Tacho look and ergo also here, the same picture. This year I took pictures and attached here, at the same time also got in contact with my dealer. I mean the two soap boxes cost together more than 80 mille and then one gets this miese Ford quality still under jubiled. This year is actually a change of our V 50, but I believe here no more Swede to the house. Have you know how to write about the same problems in the V70 STlam!
