Trek alpha 4900 vs Univega 804

[Abadarider]

Hi guys, hope you can help me decide. My bike was stollen and I can't afford a new bike at this moment. I'm going to buy an used bike for the first time but I'm not familiar with none of my options: Used trek alpha 4900 with some fixing to be done for 150 or an used Univega 804 for 220 with no fix to be done? Thank you, AbadaRider

Any advice here?

What year model are the bikes?

What repairs are needed on the Trek?
