My girl friend and I are looking for a car.

I'd like one that will take a bike inside, in case I need to let it stay in the car overnight.

Does anyone own one of these cars, and if so, will a 29er fit in the back?
- VW Lupo
- VW Polo
- Opel Corsa
- Fiat Panda
- Skoda Fabia
- Fiat Grande Punto
- Renault Clio
- Ford Fiesta

Suggestions? At the moment we are leaning towards the Lupo 3L.
