None really but they are old now and as such with anything of age do require attention with minor niggles from time to time, also agree there not really everyday cars not as in they would not get you from A to B as they will do this all day long better than what most of modern stuff would, its a question of whether the car still be there to get you back from B to A.

They do make very good weekend cars/show cars.

Good Cosworth's are hard to come by now that haven't been messed around with and/or trashed and by the sounds of it the one you mention hasn't, sensible power as well.
