What to look for: With a torch, look along the coolant pipes at the front of the engine for crusty coolant residue or staining.
Why it matters: A coolant pipe pulling out suddenly can dump coolant onto the rear tyres, which has caused loss of control on track and on the road, as well as risking engine damage from the coolant loss. Welding the fittings is the only permanent fix and needs the engine out, so confirming it has been done (or budgeting for it) matters before buying.
What to look for: Listen for ticking from the engine at idle, and feel for a misfire or stumble on the test drive.
Why it matters: A rod bolt failure risked an engine fire and the rocker arm defect could cause complete engine failure, and an out-of-warranty replacement engine is a five-figure bill. Knowing which engine revision is fitted and whether cover is still available is essential before paying GT3 money for this generation.
