2015 Mercedes-Benz E350 AMG – £18,990
There’s something about a convertible Merc that never goes out of fashion, and while the smaller models can look a bit…salon-y, the E class is big enough to waft down motorways but still look very, very expensive pulling up to a wedding with the roof down.
This one is in beautiful condition, only has 40,000 miles done and even though it’s pictured in front of a castle, it still doesn’t look out of place. If you want to spend less than £20,000 but have people think that you spent more than £40,000, this is a very simple way to do it.
