I have narrowed my choice down to a CLK 55 AMG and a C230. The C230 is a 2006 (20,000 miles) and the CLK 55 AMG is about 57,000 miles and is a 2001. They are both located here in Seattle and both are similarly priced. This will be a primary car and I plan on keeping it anywhere from 2-4 years. Does anyone have any recommendations on which to get and why? It is a difficult decision.
