I am new to this forum because I plan to buy my first Solstice soon. After months of researching this gem, I have narrowed it down to a very low mileage (5800) GXP for $15,500 or a used GXP with low miles (45,000) for $11,000. Both are one owners with auto transmissions. The one with only 5,800 miles has original tires that will need to be replace adding $800 to the cost. My question; is the difference in price worth 39,000 miles??
