BMW 135, 2010, Pirkkala

Additional information

Really well-kept enthusiast convertible, owned by one person in Finland, who has improved it without cutting corners, using professionals only.

More than €15,000 has been spent on upgrades!

It could probably be claimed that this is one of Finland’s finest examples. It has never been driven in winter, and it shows all over.

Two maps, selectable using the steering-wheel buttons. Map 1 is a normal 98-octane map, while Map 2 uses 50% 98-octane petrol and 50% ethanol, providing dyno-tested track figures of 545 hp and 780 Nm. Extremely quick from 100–200 km/h: 6–6.5 seconds!

In spring 2024, at 137,000 km, PPerformance inspected the car and installed:

- Finturbo Stage 2 turbochargers

The intake channels were cleaned at the same time. During the suspension installation and dyno session at BC Motors, the transmission was flushed, the oil was replaced, and a new sump was fitted.

In spring 2025, at 143,000 km, JTC-Performance installed:

Inspected in 2026; new rear tyres, two RVS treatments and oil changes, plus a cabin air filter.

Imported from the USA; it had minor front-corner damage in 2019.

Includes the standard downpipes, intercooler, anti-roll bars, etc., or all standard parts, including the air filters.

NOW IS YOUR CHANCE TO CONTINUE THE BUILD! Cars built to this standard and in this condition are unlikely to become available again soon.

It is currently running slightly rough, as if a spark plug or similar had failed. The garage suspects a leaking head gasket. Further driving is not recommended.
