Yep, bottom swivels, best way to check them is with the wheel off the ground, but not easy when you view a car.
Track rod ends and inner track rods fail too. Make sure cambelt is done, aux belt not as important as it doesn't run next the the can belt on the 197. Make sure gearbox synchros work and there is no crunching. Handbrake cables stick, mainly driver's side. Check air con if fitted as they can slowly leak gas. Seat and steering wheels wear (not just recaro seats). All bargaining points!
Good luck!
