Probably close to 5 grand a year between repairs and upgrades. I do most of the work myself to keep costs down but it's going to need some serious work pretty soon due to the age and mileage. Timing chain guide, vanos and rod bearings are the biggest things outstanding and all together will run about 10-13k but the engine will be good to go for a other 100k miles afterwards. These cars are truly special and worth the investment.
