Hi I am new here, I am thinking about buying a Hybrid bike and I came across one of my neighbors who just bought a Trek FX 7.3 WSD 17inch and his wife is not riding it, so he offered to sell it to me for $300. I rode it and it fitted me perfect. Its not a step through so I cant tell the difference in looks and it looks exactly like his 7.5. I did some research and the notable difference is the narrower handle bars and seat. Is the price too good to pass up or should i just get non-wsd Trek Fx 7.3? i need answers today before he changes his mind.

Thanks for your time.
