There's a guy on CL selling a 1990 or 1991 Specialized Sirrus (pre-brifters?), he says it's in excellent shape but needs a tune up. He's asking $175. There is no picture and I'm going to look at it tonight so I wanted to ask you all if this seems like a fair price and what else can you tell me about this make and model from that time period. I haven't found much of anything by Googling, anyone here know alot about old Specialized bikes? And is there anything I should look out for when inspecting the bike?
I'm just looking for a decent commuter/wet weather bike for a cheap price and that's where my interest lies with this bike.

Thanks,

Andy
