2000 Volkswagen New Beetle GLX 1.8T Turbo 2dr Hatchback
This was a fun car. But its low level of quality really stinks. Something was always broken. The bulbs for the headlight are impossible to change if the plastic mounting/locking device for the headlight assembly break (the dealer confirmed that was the case). 10,000 miles before the timing belt was due to be changed the tensioner broke destroying the engine. And because VW makes the engine mounting holes different for different models with the same engine you can not interchange them. This became a pricey repair ($7,000 before it was done). The airbag and a sensor both went bad. Several sensors went bad. It was a nightmare. I was very happy to get rid of it.
When it worked it was fast and fun to drive.
Improve quality, redesign headlight assembly, make battery easier to change, etc.
