Looking at getting a 2009 135i. The car has 89,000km on it and has never been driven in the winter. What has your experience been with the N54 engine and it's reliability beyond 100,000km?usps tracking showbox speed test

Engine and transmission is bulletproof. Just expect to do valve cover, oil pan, oil thermostat housing gaskets and if manual, rear main seal !!!!
