2009 Bmw x3 (engine seized)

Car has been parked up at my mechanics for 4 months now. Was in everyday use as a 2nd car before that and it was running well. Turbo went but didn't realise what it was. Drove it for a few miles until I got it home. Replaced the turbo but the engine seized immediately. Too much oil dumped into the engine or something like that so it seized. Its a great buy for someone able to fix it. It wasn't worth it for me as I've spent a lot on it replacing the turbo and I had to buy a van in the mean time so don't need it. Black leather interior. Clean inside. One mark on the front corner of centre armrest. No photos atm but can get some if needed. Please only message if genuinely interested. Only 225000 kms
