This is my 5th 3-series, and 4th e46 (e30 325i w/ 90k miles, 325xi, 330xi, e46 m3 csl replica). I am a mechanical engineer, I do all the work myself using all OEM or better parts and BMW diagnostic software. I have a lot of the records since the car was new, every book, two keys, original window sticker, CPO letter, receipts, etc. mileage is ~139k and goes up slowly as I still drive it.

Car is by far the most mechanically sound clean e46 on the market. Interior is super clean, alcantara is perfect, no check engine lights, never smoked in, no smells or stains, doesn't leak or burn a drop of oil/coolant, gets 28 mpg, always use 93 gas, all original panels and paint including windshield, no shutters or pulls at speed, clutch and flywheel have zero chatter. Better chassis balance and steering than my full csl replica m3.
Honestly the most enjoyable car I have ever owned, google reviews about the ZHP and everyone will say they are the best daily drivers at any price However, I am die-hard BMW enthusiast and am liquidating my cars (sold my engine swapped 330xi, sold my m3, selling this and my California alpine white e30) to buy a land cruiser for the winter and an e30 m3 for the summer.
