The Catalina 27 is a good starter boat, fairly roomy for its size and sails well enough. Wheel steering would be unusual and likely not factory, so look at that installation carefully.
Furlers can be bought from a variety of vendors, probably run you around $1500-2000 installed at a minimum. Do a search on something like Yachtworld to get an idea of asking prices, remembering that most deals nowadays close somewhat lower. Locally here an average C27 might command between $5 - 10K depending on condition and equipment, with most selling quickly at the lower range.
The low-hours engine is a plus, the indoor storage is another. Cushions are no big deal but will cost some and so any offer should take the 'missing' bits into consideration. For peace of mind and insurance reasons a survey should be done prior to finalizing any deal, as usual.
Sometimes called 'the Chevy Malibu of the sea; I reckon this boat has been the introduction to sailing and boat ownership for thousands.
