Porsche 944

Start with identity, paperwork and originality. For the Porsche 944, the strongest cars have continuous ownership history, matching numbers where applicable, original books and tools, factory build documentation and evidence of work by manufacturer-approved specialists. Documented cambelt service, original paint, manual gearbox, unmodified turbo system (where applicable) and full history.

The 2.5/3.0L Porsche inline-four is durable; cambelt and balance-shaft belt service every 4 years / 60,000 km is non-negotiable. A proper pre-purchase inspection includes cold-start behaviour, ECU diagnostics and fault-code history (where applicable), leak-down or compression testing, underbody photography, suspension and chassis inspection, brake condition and a long enough road test to expose heat-related faults. Deferred maintenance on a car of this class is almost always more expensive than buying a better-sorted example.

Use a paint-depth gauge, lift access and a specialist familiar with the model's factory panel gaps and finish standards. Collector value is dramatically affected by structural repairs, refinished panels, poor paintwork and missing factory trim or option content. Documented cosmetic refresh is acceptable; concealed accident or fire damage must be priced severely.

944 Turbo, 944 Turbo S and 944 S2 lead. Standard 944s in original colours and with documented service history are the analogue value entry point. Specification, colour, options and limited-build variants move values significantly. Buy the best-documented example in the most desirable specification you can justify, rather than a tired example of a rarer derivative that will need years of corrective work.
