Don't know about that particular car but I look for 48" floor to ceiling. That's the key dimension because that's about what I need to stand a bike upright. Front-to-back, with the bike's front wheels off, you need around 4 1/2 to 5', I doubt side-to-side will be an issue. You can put the middle bike in first handlebar to the front or turn all three handlebars at an angle.

If you don't have 48" height, you'll have to get creative about tipping the bikes on their sides or something. When you start doing stuff like that, you can force feed 3 bikes into almost anything. Since you're buying a car with transporting bikes in mind, however, that would be a deal breaker for me.
