Which used Mini Clubman estate should I buy?
Unless you need cheaper insurance, you’re better off going for the 122bhp 1.6-litre petrol Cooper over the 98bhp 1.6-litre One. It will give you similar fuel economy, will only cost slightly more for road tax and gives you much better performance. The 184bhp 1.6-litre Cooper S is fun but costs more to run, while the 208bhp JCW cars are very rare.
If you really need the economy of a diesel, look for a more powerful 109bhp 1.6-litre Cooper D from 2008 onwards, because modified parts prevent the turbo problems of earlier examples. The 2.0-litre is stronger still, but the added expense isn’t worth it unless you really want the most powerful version.
