Extended Auto Warranties, pro or con?

Years ago, these did not exist. You just took a chance when you bought a used car. But times have changed. People in the Ford Plant, are you seriously putting out a substandard product to keep these cling ons in business? Let's add another middle man!

Can I swap the car I want at a ford dealership?

If I have put a deposit down on a brand new car to be delivered to a dealership. However I have changed my mind on what car I want. The car needed to be sent to the dealership however it may not have been yet as i'm due to pick it up in roughly 2 weeks. I would still spend money on a different car however this one is second hand and a little bit less. The first car was on a finance plan. This car I'm willing to pay outright as i could get a loan for it.

I know i have signed a contract for that car. How likely is a dealership to re negotiate. They probably havnt spent any money on the first car yet so hopefully they will let me put the deposit towards the new one.

Can I change the car I want at a Ford dealership UK?

I have recently paid a deposit to buy a brand new Ford car on PCP. The monthly payments are affordable. I have also signed a contract Declaring that I agree to purchase the vehicle.

Two things have creeped up with this brand new vehicle. I asked the dealer if this vehicle had a DAB radio and he said yes. On further research it turns out that the DAB is an optional extra therefore I had been told wrong information as the DAB radio is not an optional extra I paid for.

The second issue is the finance option I chose to pay for the car. It is a PCP meaning I have a balloon payment at the end of the finance. I did not originally want a PCP however the salesman persuaded me by leading me to believe I could use the Balloon payment as equity to put as a deposit for a new car when the time is up. It turns out on further research the the only equity I get would be the value the car is above the ballon payment value.

I may be wrong. This is a brand new car that I haven't physically seen. It will be available for me to pick up in roughly two weeks, meaning that It may not have been dispatched to the dealership yet. I do not have any evidence of misleading information however I have one witness and I know what they said.
I feel as If I was mislead into a sale that would benefit a dealer a hell of a lot more than me. I'm happy for them to keep the deposit I paid towards a different car maybe second under a different finance plan.

What are my rights?
Am I wrong about the PCP equity

Power steering issues? Electrical Issue? What is the root cause of this? 2003 Ford Tarus?

I bought a used car about 8 months ago and have been having issues with it. I'm going to start at the very beginning and give as much detail as possible. First bought the car, owner said he put a new battery in because it'd been sitting and wouldn't start and that it needed a new water pump. My uncle (self employed mechanic for 30 years) replaced it for me.
Was running fine until summer hit and I started using the air. If I used max A/C and drove for more than 20 minutes then parked my car and let it sit for 20 or more mins it would not turn over, it'd just sputter or start up, sputter then die, even while giving it gas. I'd have to sit and wait for it to finally turn over and once i started driving it was fine. Took it to my uncle and he said it was the starter so he replaced it. **Note: i had no other issues before this moment.**
When I got the car back nothing initially seemed wrong. I drove it for awhile, under a month, and my gas gauge started having issues. Sometimes it would work, sometimes it would read more or less than what was really in the tank. And it doesn't matter if the tank is full or empty. The check engine light came on a day or two later and i had it checked but i don't remember what code it was throwing.

My new battery is draining too fast in my car, why this?

My battery and alternator in my ford probe is new but it drains really fast after I drink only a few times but when I read online it says that I should be able to crank for 10 minutes I crank for far less than 10 minutes in the battery dies. What could cause it to die fast? There's no parasitic drain. Could the starter be bad, drawing too much amps
