I've found steel corrosion in various places but mainly in the outer sill construction (inside and outside parts). The insides of rear wheel arch tubs tend to get a bit thin so worth a check for crusty spots at the chassis side. Other places to look are around the rear shock top mounts, bottom of 'A' pillars and boot floor. The front wing support beams can get quite badly corroded also, check by opening the lower wing flaps and feeling along the beam. Aluminum areas are normally rear wheel arches, rear ends of outer sills and edges of exposed panels where riveted to steel tend to be weak and flakey. I've not found to much chassis wise apart from the usual surface corrosion or where other corroded panels are joint to or cover chassis parts. Hope this helps.
