The supermini-MPV market hasn'Â’t taken off quite as Vauxhall would have liked, but the Meriva enjoys a small yet strong following in the UK. And while 15 per cent of owners reckon the five-door has failed to live up to expectations, itÂ’'s outperformed the Astra and the Vectra in this year'Â’s survey. As you would expect from an MPV, the Meriva scores well for practicality –– 11th is a superb score for such a compact car –– but disappointing ratings for reliability and performance take the edge off.
