Ah yes. I too have a 2013 28i x3. Mine is vermillian red and I bought it over a year ago. Everyone tells me the 4 cylinder engine of this year is unreliable and is going to fail. I haven't had one problem with it at all.
Woow , only 20k for 4 year old x3 , I think it was a great price .. msrp about 39k . Today , 10 years later , its difficult to find a decent one for 10k. Thanks Covid..
