trust me, you don't need the test drive.
they handle like no other fwd cars, especially the prev gen ones (see the lighter ones). Dad also had a 156 (220.000 km or so just with the clutch substitution at 190.000 km), and I did practice with it before of taking my license. It was simply awesome, so driver focused, agile and nimble despite the low power and heavier front (diesel engine, 105 hp).
seriously, those cars are fantastic, and also the quality of the interiors is excellent.
the 156, after all those km, had the driver seat in very good condition, while the Lancia Phedra one (PSA project), after 130.000 km was in worst conditions.
Obviously you have to check the car properly, and test drive the very car you would buy to be sure everything is fine (perhaps bring with you your trusted mechanic).
