As far as the lights go, it's just a cool factor, you will never really need them IMO.
I don't think the jump seat is a needed option in a V-Drive, in a DD yes.
I think the soap pump is kind of lame, but that my opinion. I'd rather just have my bottle of joy. I'm too lazy to refill the pump.
Like Brad said, the bimini is a must. I wouldn't pay for it from MC though, go to a shop that can do the work and get it for a lot less . You can always have the MC logo sewn in if you want. You can get cooler designs from different companies too. A guy here in Kansas had an American flag style bimini made to match his '98? Pro Star 190 Stars and Stripes. The heater is a nice option. IMO you don't NEED it unless you are riding "out of season". I've never sat there in the summer and said "man I wish I had a heater" no mater how cold it was. We ride a lot in the winter in 40 and 50 degree weather, than it is a must. It really only helps the driver and a passenger if you have a hot tube, so if you want to make them happy go with it.
