Sales advice DS3 Hdi 110

Hello here in the Zitrönen-Unterforum! I’m on my way to swap my very thirsty Mini Cooper S for a DS3 Diesel. Planned would be the Hdi 110 in the SportChic equipment (+ Selection package). Before I sign the contract next week, I just want to ask what experiences – positive as well as negative – you have made with this car, what I should possibly consider etc. pp. Thanks for every feedback!
