Based on limited information, not worth it. Up to you. Condition is everything. The early 1980s Ross had some nice bikes, but that company went bankrupt in 1988. IMO, Ross couldn't decide whether they were going to make good stuff, or department store junk. Huge variation across their line. In the early years, the Mt Hood and Mt Whitney were very nice, along with their signature line of road bikes.
Older bikes tend to need a lot of maintenance. Unless you do all the work yourself, its easy to end up upside down value wise on a bike.
