Who said anything about it being a daily driver? The OP just asked "If you had to have a 4 door car, show me what you would drive" so I'm thinking I have the Stang and the M5, dreaming is free :winksMaybe it's just me but I don't see the point of having a daily driver that's more powerful than your weekend/fair weather/cruiser vehicle unless said vehicle is a true classic car. I just couldn't see my myself having a v6 or a v8 Mustang as a fair weather car and use something like a BMW M5, or Mercedes E63 AMG sedan as a daily driver. I would be consumed with having that kind of power all the time at my disposal that anything else would just feel like a let down. For me things just have to be kept in perspective. If my daily driver is pushing 400hp, then my cruiser or "fun" car had better be more power and exciting than my daily driver.
