I am well over six feet tall and overweight. I work at home and drive very little. I nonetheless like an entertaining car when I do drive. At present I have a 16 year old Vauxhall Vectra, with less than 60,000 on the clock which suits my needs very well. What should I replace it with?

Ideally my next (second-hand) car should be fun to drive, have two doors and easy access. I would love an Opel Monza but they are too old to consider now. Would you say a Porsche 924 would fill the bill in terms above all of interior room? Or do you have another suggestion?
