JD BYRIDER Completely taken advantage of Madison Wisconsin

I purchased a van from JD Byrider out of Madison WI about the 8th of November. Thee night I got in it to take it for a test drive, after 4 hrs of paperwork and this being the second day my husband and I had to drive there, we drove it for 5 minutes down the block and that was our test drive. When we got back it was close to 10 o'clock and we still had a two hour drive home. I mentioned to Rebecca that there was some clunking noises coming from the front end but she contributed that being from sitting on the lot for 30 days... So we headed home in our " new" used car and have had nothing but problems since. I called in to get that same problem looked at and set up an appointment. Took the van in and left it overnight the first time. The mechanic said he fixed the outer tie rod end and aligned it. I came and picked it up and Nothing was fixed. The oil got changed as far as I know. I didn't look cause I didn't think I needed to. So I call back right away the next morning and tell the mechanic nothing got fixed so he said to bring it back in but I couldn't get in for a month. So come March 3rd I was on for another appointment. I brought my car Thursday and I called Monday and they said they didn't even know where the clunking was coming from yet and they still have my car as of 1:09 p.m. Not a happy customer at all. They just got my tax money and have been getting 200 every 2 weeks since November 8th!!
