Whatcar.com is always here to answer your motoring queries - each week, we put your questions to our experts to try and make your life easier.
This week, you're been asking which colours affect resale values of cars, whether you need to change your headlamps for going abroad, and whether an internet business is legitimate or not.
To find the answer to these and other questions, read on.
Click here to submit your own question. We publish a selection of answers here every week. Please be aware that we are inundated with questions and can't promise to reply to every one.
Before you send in an e-mail, you could well find the answer you're looking for in our advice section and glossary. Click here to go to our advice section, and here to take a look at the glossary.
If you're after advice on which car to choose, remember to tell us what your budget is and what your buying priorities are. Tell us if you're more interested in economy than performance, for instance, and what you'll use the car for.
