Mine isn’t terribly exciting, I like mid-size luxury cars like the E-class, Lexus GS or Cadillac CTS the best. My logic is that these cars are usually different enough from the standard family car to warrant the price. Plus they usually have plenty of power with nice engine options and still can be fun to drive. If I was stuck with only class of car to purchase for the rest of my life, I’d be happiest with this.
Close second is sport compacts like the GTI, Focus ST or Civic Si. Nice and practical with plenty of power, but not too pricey.
