A friend of mine does all his commuting in a Cirrus and swears by it. it once took me 9 hours to get back to London from Bradford by car and he was there 8 hours before me !!
If you can afford the Avgas, landing fees and taxi to and from the airfield then it's definately the way to go. Personally, I'm about £999,999 shy of a millionaire so a few more years before I commute PPL.
