not just 2006I am looking for an R171. I'be heard to stay away from the 2006 model year because of engine problems. I did a quick search and found i can get a data card with the engine code. Is there anything else that I need to check on these cars? Are there any years that I need to avoid? I haven't ruled out buying a R170 if it's clean w/low miles. Did the R170 have any major issues I should be aware of ?
