ill agree with audi, i dont really like mercs though, my mom has had a couple of them and meh...too heavy, weird handling, etc...might be different for the smaller ones though, she had bigass S-classes
i had an older A4 until last december...manual 2.8 quattro...LOVED that car, only problem was it had 130,000 miles on it and it started breaking all the time and those things are way too expensive to fix
so my parents said theyd help me get a new car for graduating, id pay 7 grand and they would pay the rest...i wanted to get a new A4 but since audi has been doing better than all the other german auto makers lately, it was impossible to 1) find a new A4 quattro in my vicinity, and 2) afford one once i found it
BMW, on the other hand, was practically giving cars away...i wanted a 3 series 4-door with the new X-drive, but they're brand new and nobody was haggling on them...
meanwhile the best dealership in town offered me a crazy deal on a 2008 X3 with like 5000 miles on it...it doesnt LOOK as sweet as some cars, but it's ostensibly 4WD and the straight-6 is an amazing engine, so i like it for now as a good mountain car, it held up well in Colorado last season and im planning on using it again
ill probably trade it in toward an A4 or an X-drive 3 series eventually, but for now i really enjoy the thing
