What to check on a S1 Elise
3 model-specific things to look at when you view one. They're a starting point, not the full inspection.
Head gasket and cooling
What to look for: With the engine cold, remove the oil filler cap and look underneath it. A milky, mayonnaise-like residue is the thing to note. On the drive, the temperature gauge should rise steadily and then hold. Ask whether the head gasket has been replaced with the improved type and steel dowels.
Why it matters: The K-series holds a small amount of coolant, so a leak or a damaged radiator can overheat it quickly, and overheating leads to head gasket failure. Early cars used plastic locating dowels that let the head move; most have since been updated with an improved gasket and steel dowels. The front radiator is prone to corrosion, and many owners have fitted an all-aluminium replacement.
Cambelt age
What to look for: Check the history for the date and mileage of the last cambelt change, and for servicing every 9,000 miles.
Why it matters: The K-series uses a cambelt, due every four years or 54,000 miles on most models, and every three years or 36,000 miles on the Sport 160. As many S1s cover low mileages, age is usually what makes it due.
The steel rear subframe
What to look for: From underneath, look at the steel subframe at the back of the car that carries the engine and rear suspension, and at the front wishbone mounting points. Look for flaking, scaling or rust holes.
Why it matters: The aluminium chassis doesn't rust, but the steel rear subframe can rust badly and the front wishbone mounts are prone to corrosion. Galvanised replacement subframes are available, and one already fitted is a sign of a car that's been looked after.
