The trouble with a great many car video reviews is they are a press launch day and normally abroad, so you are seeing Europe based models. These are not what we get with the UK spec. Take my Tarraco FR Sport for example. All left hand drive vehicles come with dynamic chassis control, Beats audio system, heated bucket sport seats, and quite a few other techy bits, not included or an option on UK models. In Europe they only offer the FR which comes with a lot of options. In the UK we get the choice of FR, and FR Sport with only sunroof and spare tyre as the only options.
Like others have said, research is the key, I even go on other countries configurator’s to see what’s different.
