The mirrors I have used for the past 3 years on my V70 would fit, I'm sure. They are Maypole strap-on mirrors. You will hear a lot of criticism of them on here, but I find them just fine. They are fixed by two rubber straps that go round the back of the mirror, and they will fit almost any car. Some currently on ebay for £14.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
