Hi! Greetings from Vermont. Proud owner of TWO 525I's; a 1989 with the M20 at the shop at this time. The prior owner let the engine overhead at 133k and have to replace the cylinder head, should be out next week with rebuild engine. The second one is a 1991 with the M50 engine, purchase in a auction for $125.00, so far expend $600.00 with new rotors, pads, sway bar, outer tie rod, cabin filter, brake sensors, fuel filter, oil change, O2 sensor, air filter, plugs, now I need to reset the SBS and ready for inspection and planning more improvements in the future.
