public transport and a car cover. or rent a garage with the money you save.
then when you do drive it , you will enjoy it more as you wont be going to work.

i use the train for work, the car is for when i want to drive it. avoids the traffic jams and the cost and hassle of parking. 

how long does it take you to get to work on train?and how long by car?

i think train then. as its a heck of a lot of mileage youl be clocking up, for the sake of 15 mins extra and maby a few pounds more itl keep your cars mileage lower and then something to look forward to for when your coming back from work and the weekends . i use my punto for work.i think id get bored of the 500 if i took it to work and back as it would just be like a everyday car.i like to keep the special  feeling of having it as a "night out and weekend car" .

Your anti perforation warranty covers the body from rust for 8 years.
It must have an inspection at the relevant service intervals and wont cover any part of the body that has been damaged.
In other words if you catch the sill on a low wall and then it rusts it wont be covered

I hate trains with a vengeance but to be fair, the real issue is the London Underground. I started a new job near Southwark bridge back in July. 45-50 minutes to Marylebone was OK-ish, but the same again on the sauna tube packed in like sardines? I lasted 3 weeks and bought a motorbike. Saves at least 30 minutes daily, some days more like 45 minutes - and more if I had missed the train home I was aiming for (happened about twice a week due to tube delays)

Borrowed my brother's scooter for teh frist couple of weeks, that was costing me £6/day rather than £18+ by train, but as I said to the wife, the scooter is free and one of my own wouldn't be

Still reckon the break even point is around 15/18 months depending on service costs but the bike will still have more value than a bunch of used train tickets - and I gain 3-4 hours a week more with my family

The A500 has suddenly gone from 300 miles/week on average to barely any as it now only gets used some weekends

How about alternating between the two every month in winter and bike/ scooter to work in the summer?

I motorbike in the summer, the downside is like this morning, lovely day, full tank, sandwiches in the top box, Yorkshire Dales calling. Nearly never made it to work.
