You don't say how old the car is, so assume older than 3 years, and warranty offered with the car 1 or 2 years?
I'm sure there will be others out there with sunroof, which helps lighten up the cabin and DCC for a softer ride, if required.
Personally, I would go for a car with extras that you will find useful, and at some stage, will make it more saleable later on. I think sat nav is a given these days, but you may be able to retrofit a head unit. More knowledgeable people than I can advise.
Hope that helps.
