1960 Porsche 356 B 1.6L Petrol · 4300 RF

The 1960 Porsche 356 B presents a stable but slowly worsening roadworthiness trend, culminating in the most recent test on 11 September 2025 at 75,234 miles. That pass was clean of major mechanical failure, yet the tester flagged two advisories: corrosion on the nearside rear suspension component mounting prescribed area and a slightly chafed offside front brake hose. The corrosion advisory is not new. It appeared in the September 2024 test at 74,919 miles with identical wording, suggesting the affected mounting area has been deteriorating gradually over at least the last year rather than failing suddenly. The brake hose chafing is a fresh defect for 2025 and warrants prompt attention, as chafing can progress to a dangerous fluid leak if left unchecked. Mileage accumulation tells a story of very light use. Between the August 2023 test at 74,612 miles and the September 2025 test at 75,234 miles, the car covered just 622 miles across more than two years. Annualised over the full 66-year life, that is roughly 1,140 miles per year, which is exceptionally low. Such low annual mileage often points to long periods of standing rather than regular use. Extended storage can cause seals to dry, rubber to perish, and localised corrosion to form on exposed mounting points, exactly the kind of pattern the rear suspension advisory hints at. A buyer should focus the physical inspection on the rear suspension mounting area that has now drawn an advisory twice. Probe the nearside mounting point thoroughly for pitting, flaking, or soft metal, and check the corresponding offside for similar corrosion. Suspension bush condition and any play in the rear trailing arms or anti-roll bar links should also be assessed, as corrosion at a mounting point often accelerates wear in adjacent components. Inspect the offside front brake hose where it routes through the inner wing or subframe, looking for any exposed fibres, swelling, or abrasion marks. If the chafing has reached the reinforcement layer, the hose must be replaced before the car is used on the road. Beyond the flagged items, the low-mileage storage pattern demands a broader check of perishable components. Tyres may look legal but could be aged past their safe service life, and flexible brake hoses elsewhere on the car may share the same deterioration risk. Fuel system integrity, including tank and flexible feed pipes, deserves attention after long periods of standing. The mechanical record itself is reassuring, with two consecutive clean tests in 2022 and 2023 and no major failures in the visible history, but the emerging corrosion and fresh hose chafing indicate this car needs careful hands-on verification before purchase.
