I know the garage isn't up for review just yet, but a minor point occured to me whilst fiddling in My Cars earlier.

The algorithm that interpolates cost per year/month from the raw figures is a bit too literal, in that if you have owned a car for less than a year, anything you spend on it gets factored up to produce an annual total.

I can see exactly why this would happen, but it does paint a rather inaccurate picture of annual running costs until you have had the car for at least a year. Perhaps a better algorithm would be to determine if the time period is less than a year and if so leave the annual cost as the grand total and the monthly cost as 1/12th of this.

e.g. You buy a car and spend £500 on servicing and £300 on tyres in the 1st month of ownership, apparently the annual cost would be £9,600 in the 1st month, gradually reducing to the true figure of £800 by month 12!

Yep, it's fair comment. To be honest I put that part of the site together in an afternoon and the rush job is still haunting me! I will attend to it ASAP!
