Hello to all of you. I don't know if it's permitted but I would like your advice...

I'm thinking about selling my car. I looked online and at differents garages about the general car value and i don't know what to think about it.

So I have a mitsubishi mirage 2018 GT CVT (130k km) with remote starter.
I also have brand new summer tires on mags and used winter tires on rims...
I just got the distribution chain and water pump changed like a week ago. I also had the engine replaced at about 60k km.
Front brake done like a month ago and rear brake done not even a year ago... Battery change 2 years ago...

So I'm saying all this because I was offer 6000$ and I feel like this is not enough ?

I would like to know what you all think about that.

Thanks in advance !!
