TXpeople - why cars exempt from capital gains tax purposes

Because they're classed as a wasting asset - ie they have a life of less than 50 years. However, classic cars can sometimes be kept longer than that and often go up in value over time, so people do buy them as tax free investments.

Further to the above, which is all correct and true, if cars were treated as taxable, this would generally result in capital losses being claimed as most cars lose value over time.As these losses could be set against gains this might well result in government losing revenue.

For business purposes this would in theory be taxable.In practice it is unlikely to occur due to natural tendency for cars to lose value. What is far more likely to be examined would be balancing allowances and charges.Not sure what you mean with second question.
