I have a 2007 MazdaSpeed 6 for sale. Best car I have ever owned. I put 200,000 on first engine and have 161,000 on the second, a factory engine from Mazda. Car runs like a charm, always has, but family expanding and SUV is now required. What should I sell it for and are there any buyers out there for a great car that runs so well, especially at high speeds ?
