2013 Fiat 500

Selling my Abarth. Just had a full service done to it, plugs, oil, filter, etc. brand new windshield, door motors are all new. Just paid the registration and passed smog. I noticed last week it didn’t have as much power (no check engine light). Took it to a mechanic and he replaced a part and now it’s throwing a code. He told me it’s a bad turbo but honestly I don’t have time for this car anymore. It’s one of 5 I own and I’m ready to part ways as it stand today. It drives just fine just doesn’t have much boost. This car with this low of miles go for 10k+ so please don’t try to negotiate with me.
