 I bought this car new and had it ever since. Never seen a mechanic since purchase. I put a custom bodykit, 20 inch rims. cold air intake. Car is awesome and still drives like new. Wished i had got the stick instead. Gas average 27 (city/hwy). that is very good. Good power. I don't know about those who had bad mechanical experience with bmw, But I would love to get another i35, 335 or m3 someday.
