You could always buy it and then ride it home
Lightweights!
We've had two adults plus two kids plus FOUR bikes in the back of our Passat estate.
if you have a family member or someone with a bike you could always ask them if they could try fitting it in the back, least then you have an idea about space. i have a little clio that loves my bike when the seats have been removed, so maybe that is something to tryAs a plan B I might have to come to the UK to buy a bike, I know you can buy bike racks, but if I took the front wheel out of the bike and I dropped the back seats of my car would the bike fit in.. I have an Astra hatch 4 door.. or is that pushing it a bit..
Cheers
