ABOUT THE 2010 BMW 128CI CONVERTIBLE
The 2010 BMW 128i Convertible is the entry-level open-top model in the E88 1 Series range. It uses the naturally aspirated N52 3.0-litre inline-six, rated at 230 hp and 200 lb-ft, and drives the rear wheels. This entry covers the version with the six-speed automatic; a six-speed manual was also available.
Where 2010 sits
The 1 Series convertible reached the US in 2008, making 2010 its third model year and a largely carry-over one. The 128i sat below the twin-turbo 135i and was the choice for buyers who wanted a smooth six-cylinder and lower running costs rather than outright pace.
What it is like
The N52 is a free-revving engine with a pleasant sound, and the 128i’s softer suspension gives it a more comfortable ride than the 135i. Steering is hydraulically assisted and well weighted. The power-operated fabric roof keeps weight down compared with folding-hardtop rivals, and the cabin seats four, though rear legroom is tight for adults.
Buying one today
The N52 is regarded as one of BMW’s more robust engines of the period, but the electric water pump and thermostat are known to fail, and oil leaks from the valve cover and oil filter housing gaskets are common with age. On convertibles, inspect the roof fabric, the hydraulic mechanism and the drain channels. Rivals included the Audi A5 Cabriolet, Infiniti G37 Convertible, Volvo C70 and Volkswagen Eos.
