Ross Grand Prix
I just picked up a beat up Ross Grand Prix for pretty cheap and want get some opinions on if I should be restoring it or replacing enough parts on it to be enjoyable to ride. My guess is the latter after doing some research on the forums, I don't think it's one of the sought after ones. Here's some details:
1) It's a Ross Grand Prix, my guess is from the 70's judging by the cottered cranks.
2) On the top tube it says "Professional Model".
3) The headbadge says "CBC New York" and "Import Div"
4) The tube shifters on it say "Shimano III"
5) Rear derailleur is "Shimano Eagle"
6) Front derailleur is "Thunder Bird"
7) Brakes are Dia-Compe
8) It weighs a ton

At the lower end, the Ross frame is the best part of the bike. Models such as the Eurosport and Eurotour had one-piece (Ashtabula) cranks, which limited the ease of upgradability somewhat.
Your Grand Prix is slightly better quality and has standard bottom bracket threading which greatly broadens your crankset options.
What upgrades did you have in mind?
My Eurotour has benefited from several inexpensive upgrades. It's my best-fitting, most comfortable road bike and I ride it almost daily.

Not pictured is the three piece alloy crankset I added last Fall. It still has the all-steel wheels but that will change as well, if I can scrounge some used 27" alloy ones.

I'd replace any part that doesn't function (that chain don't look too hot) and ride it 'til it doesn't work any more.
A heavy bike like that is totally worth riding when you don't have something else you'd rather ride...
but is it gonna be good enough after upgrades, to be worth the cost of upgrading?

I have a feeling I'm gonna destroy the cotters while I take the cranks apart, so maybe the cranks will be the 1st to be upgraded (other than the rusty chain and dry tires). Then again, I do like the classic look of the cottered cranks so maybe I'll just try to find some cotter pins somewhere.
I like what you did with your Eurosport.

Your's may be different of course, I'm no Ross expert. But one of the first issues I ran into was that the steerer tube is that undersize diameter, i.e. it won't accept a standard 1" (22.2mm) stem. I haven't had a chance to do anything to mine other than clean it up.
