If you want a reliable and comfortable convertible then the Focus is a good choice. But be aware that early cars, especially those built in the first 12 months, can suffer from problems with leaky roofs, so it's worth checking that any car is watertight. Diesel models will always be priced a little higher than the 2.0-litre petrol model. The entry-level 1.6 CC-1 isn't as quick but could prove to be a bargain.
Even though the Focus Coupé Cabriolet is an all-weather car, it will still be easier to sell in spring and summer as the warmer weather encourages buyers are to look at convertibles. Buyers might be put off by the reports of leaky roofs so it's worth proving yours is fine - even if it involves a bucket of water.
