If going midsize, the 2006-2008 Mazda6 2.3L is one nice car. Price would be around 300k nowadays. Its size straddles between compacts and midsize cars of that era. Even in stock form, it's a looker. If looking at the 7th gen Accord, look for the 2.4L model. Most say it offers better FC over the 2.0L model. If you want something fast, follow what GTi suggested and opt for the Accord 3.0L V6.
