where do you live??? If your from california or oregon, I can save you a ton of $$$ on insurance. I don't like the ti, I prefer the i, I own a 318i and love it very much. But if the ti is your preference, then go ahead and buy it. I don't know much about the ti but I assume parts are easy to get and believe that any bmw is dependable. Just make sure you Thoroughly check the car, like the oil, fluids, leaks, accidents, and if there's a service history look at it. Question eveything before you buy it, afterall its an investment. Good Luck!
