Which Volvo should I buy next?

Hello, I’m driving the 2nd Volvo. I’m very satisfied. Currently for 9 years a 2001 V70 II with gasoline and 140 hp, it’s the best car I’ve ever owned. The quality is outstanding. Now I think about buying another one. I’ve looked around…the newer V70 III gasoline has unfortunately heard a Ford engine…I don’t think that’s so good…do you think that’s so advisable? What do you think? I’ve also looked at an XC 60. but rust spots on the fenders. I didn’t even know that from my Volvos…the rust?! When did they introduce this “pgrade” of the rust flowers? I need a big station wagon for my business with AHK and gasoline engine. I unfortunately drive a lot of short distance in winter, therefore I prefer not to have a diesel…I heard, then they will break quickly… I want to spend about 3000-6000 euros. What would you recommend me for one?
