Unwise. Diesel never made sense for coupes anyway. You buy a coupe to tell people you aren't a sales rep or a taxi driver. Then, as soon as you start it up, it rattles like an old lorry and tells people you're a cheapskate. And that's on top of all the problems associated with the emissions and the unreliable emissions equipment on a diesel. Unless you do 20,000 miles a year or more, need a very big vehicle such as a pick-up or a van, or need to tow something, don't buy a diesel.
