J.D. Byrider review: mechanical pro8lem

while cleaning out a car I got from jd byrider over a year ago, and am forced to surrender due to lack of finances to continue paying for it, I found a vise grip caliper tool still attached to the driver's side rear strut. the tool has as much rust and wear on it as the strut, and since this is the first I have heard of it, I have to assume it was on the car before it was made availa8le on the sales lot. does this 8reach or void the contract on our part or theirs? also I was sold a car that doesn't have the weight allowance for myself or my wife and not warned a8out it at the time of sale. that and they knew I had no jo8 or income at the time of the sale and they still gave it to me. I offered no proof of income or employment. does any of this void the contract?
