Tiburons aren't cheaply made. They are a cheap car. I mean that as to say you get what you pay for. A quality low cost sports coupe. high on style, moderate on everything else. The ONLY thing I had to do to my first 2003 tiburon in the 3 and a half years I had it was buy a new battery and a new tire. That's a pretty good run if you ask me.
I bought another 2003 tiburon a year ago and I've had a few other problems but i feel they are mostly the fault of the previous owner. Some weren't though. I had to buy a new alternator, new tire, new battery, new inside and outside door handles for driver side door, new door lock actuator, new window motor, and i think that's about it for a car thats 8 years old and has over 100,000 miles on it, that's not bad. definitely a quality car. You should read online reviews from people that review cars for a living. Sure we own tiburons, but we have a narrow scope of what quality is like across the board...
