WHAT To look For WHEN Buying AN SC: THE SPECIALIST’S VIEW

Phil Raby says that smooth running and an even idle are paramount: “If there are flat spots and lumpy idling and the cause isn’t simply poor plugs or leads, then investigation needs to be systematic, working through the K-jetronic to the ignition and timing. Check that electric mirrors and seats haven’t seized and ensure that if Cup or non-standard wheels are fitted they have the correct offset.

A good 915 gearbox should change without baulking when warmed up. People force them from cold and they get worse and worse. Be on the look out for any signs of corrosion under carpets and on aluminium brightwork.”

Paul Stephens adds that engine maladies are often attributable to broken studs: “The cylinder barrels become loose on the block, so the engine loses compression. We replace with 993 dilivar studs which don’t fail; if original the electronic ignition is probably worth replacing, and don’t let anyone kid you difficulty engaging first is normal – it’s the sign of a gearbox in urgent need of an overhaul.”

Both specialists stress the need to examine the underside for corrosion, especialy the vulnerable B pillars, and Paul Stephens cautions if buying a ‘restored’ Targa: “When you take the sills off the whole Targa shell flexes, so this must be done with the car secured on a jig. Otherwise the panel gaps don’t line up on reassembly and the Targa roof won’t fit: the car doesn’t feel properly taut and water gets into the cabin.”
