Which used Mini Convertible sports should I buy?
Given the potential long-term reliability issues with the diesel model, you might find that the initial savings made in fuel costs could be undone by expensive maintenance bills later on. It might therefore be more cost-effective to go for a petrol model, with the 122bhp 1.6-litre Cooper providing the best blend of performance and running costs. If insurance costs aren’t a concern, a Cooper S or faster John Cooper Works would be an even more entertaining way of going topless.
Choosing a 1.6-litre Cooper also means you get a decent level of equipment, but look out for an example with the Pepper or Chili packs to get more kit.
