not my place to say but i think this is a bit uncalled for "

" as it was just a statement and observation as mazdalver said they do agree with the cons being rust. and yes every car will rust, it depends on when. we have a 2002 ford taurus ( my dads car) has rust on the rear wheel wells.. bad, front hood, roof. its sad to see as the car has 136,000km, they also have a 2007 camry- not a spec or spot on paint or body and it has only 40,000 km purchased from a neighbour, where as the gfs parents have a 04 avalanche with 150,000 km, mint paint, but of standard body rust under, and a 2002 Silverado 1500 with 260,000 km. good paint, bad under the vehicle and lastly a 2003 maxima with 170,000 km. and good paint and so so body rust. so i mean from ford, mazda, chev and nissan, they all go in different ways. even my sisters 2000 ford taurus doesnt have the rear fender rust as bad as my dads 2002 and the 2002 has seen more washes and care then my sisters car. take it down to when it was built.. maybe who knows.
now down to the two 2010 mazda 3's. mine- rust protected since purchased, not even a spec of rust, sharkbaits ( not rust protected ) no paint rust and slight frame rust and she had rust repaired on the door pillar trim ( which there is a tsb for if it happens )
