What Car? Q&A - Introduction

In our postbag this week, readers' questions include cool (and insurable) first cars, what you're legally obliged to do after an accident, whether 4x4s will attract more company car tax, and when the new Audi TT will arrive (and we have an exclusive picture of the sporting coupe).
