Just to update this thread, we are checking out a local 128 convertible next week that is owned by a business acquaintance. He wants what I would consider to be top dollar for it, but it's a one owner car with full maintenance history and new tires, so I'm prepared to get a deal done if it's in as good condition as he claims.
I got a coupe, 2012, 141 km. Mine suffered from:
Misfire: Ignition coils and plugs
Oil leak: Valve cover gasket
Oil leak: Oil pan gasket. Not solved yet
Headlight failure: Headlight assembly
Foglight failure: Fog light assembly
Starter noise: Starter? Not solved yet
Fuel leak: Fuel pump leak
Rear noise: Both rear shocks replaced
Front shock leak: Both front shocks replaced
Ground strap
Serpentine belt and tensioner
Blower motor
