UK Driving Instructor so get asked this a lot. Your best bet is telematic insurance (black boxes) but read the small print. All companies are different and have different penalties etc. See what suits you. Don’t ignore any cars, as you can be surprised what is cheap to insure. Rarer cars, or unpopular cars can be really cheap as they appear to be lower risk. Smaller engine sizes, and adding someone experienced as a named driver can also help.
