I just bought a car 5 weeks ago and I don't like it at all.
It is not officially registered yet, but the dealer did notify the DMV of the sale. The dealer assured me it was not registered because the dealer wants me to go back and trade it in through him (Unfortantely I'd rather not do this because he is trying to take advantage of me).
I'd rather just cancel the registration and get the sales tax back and trade it in through some other dealer.
The last thing I want to do is trade this car in and have to pay full sales tax again on the new car.
I live in california (paying sales tax on the difference of trade in doesn't apply here).
