Juwel 
2004 Toyota Avalon Sedan XLS 4dr Sedan w/Bucket Seats (3.0L 6cyl 4A)
Worst car I ever owned
 Bought the vehicle new at the end of 2004-after a half year shaking and 'unsmooth' operation of the steering. Dealer found no problems. Several alignments and different sets of tires showed some improvement, but still not what you expect from a top of the line Toyota. From approx. 20k on rattling and noises from different interior parts... Now after approximately 50k the crank shaft pulleys broke (another $2k was quoted to fix this issue). In short: I bought this car since I had such positive experience with my 1990 Toyota Pick-up (now over 260k miles) and almost no repairs. However my Avalon is from a different breed: Lots of expensive repairs combined with a minimum of enjoyment.
