I think you need to get more sleep. First you say that you are talking about the Z5. Then you say that if you want 2 seats you'll buy a Z. Uuummm...you're already talking about a Z, a Z5. Given the number of cars that are discussed regularly here that have a Z in their names you may want to be more specific.JST said:
The Z5 is an interesting proposition, but it has three very strong negatives, at least as far as I can tell now:
1) 2 seats. BMW, what happened to building sports *sedans*? If I want two seats, I'll buy a Z. As Hack points out, no baby seat (or anything) is coming with the driver and his/her single passenger. Not practical.
While it does sound like an interesting car, I'm also not sure I'm ready to give up the third pedal.
