heh, I got mine as a company car for travel to and from work, and I find it suits me enough. Good enough for me and my gf. I don't carry much luggage but its enough to do the shopping rounds.
Boot will fit a small suitcase easily.
The only problem I have is ocasionally you'll meet up with friends and you can't use your car to drive groups of ppl around.
I have 3 other cars, all family sized ones and I have not really seen any time where I had to use them and not be able to use the SW20.
