An MX5 is the default choice, and I would think you would get a set of clubs in the boot OK, not very original though, and your husband will feel like a hairdresser if he ever drives it alone. Personally I would get something more interesting like a nice classic TR6, plenty of room in the boot, and lots of very tidy/semi restored examples around for sensible money, especially at this time of year. Dassie's suggestion of a Golf is a good one, its likely to be reliable and has plenty of room, but looks a bit like a pram with the top down. I like the Pergeot 309 cabriolet, looks very nice, and drives very well too. The MG TF is also very underrated and suffers by asociation with its rubbish predessor so can be had for very sensible money.
