Almost at 100k miles and I have only had to replace the breaks and the oil filter housing (cheap part). I love my Vibe, bought it with 50k on it and have put 50k on it in the last 2 years. Its comfortable enough for the average commuter and very reliable. Great for hauling stuff around, and although no sports car its fun to drive. Good fuel economy, easily get 31-32 mpg. Only a few gripes, rear visibility is so-so, paint chips/scratches easy, speakers could be better.
Back up cam? Better speakers and thicker/stronger paint.
