Don't get the 3.2, it's rubbish. You have to pay 5 tonne a year to the post office & you don't even get a peice of paper with an expiry date on it anymore. So your just paying the post office staff wages for that week.
You fill up with fuel drive to work, then you have to fill it up again because it's all gone. It's really that bad, & they're really slow too. I was once over-taken by a Reliant Kitten, might be down to the 3.2's weight though. The Kitten's made from fiberglass.
If you live in a cul-de-sac, or a quiet street, on a cold morning they wake the nieghbours up because they sound that noisey, if you leave at say 5 0r 6am for work. So you'll get letters from the evironmental health over noise.
They are really dear to insure also, i have to pay £411 a year. Ridiculous, i know!
I wouldn't get one if i was you, you'll just regret it.
