I would have to see the car, but I think you were maybe just a little bit low. Did they not offer any form of counter offer? I am shopping for something similar as well, but expect to pay maybe 48 max for something similar. I would think they would counter close to 45/46, but it all depends on color combo/options and condition.
I would most definitely go with a coupe over a convertible as well. Better resale and less maintenance.
