Just walk away mate.
For 4 grand you could get a straight cupra that will be easier to sell on in the long run.
Reminds me of when I was looking for a saxo vts a few years ago. Had my heart set on a saxo so I sold my fiesta and was relying on lifts from my parents and friends for a few weeks.
Was looking for ages for a nice example but unmolested, clean cars were hard to find. Out of the blue a white saxo vts came up for sale in autotrader about 20 miles from me. It looked like the one. Low miles, one owner, unmodified, FSH.
Not being mechanically minded I took a mate with me that works as a mechanic. Went to see the car and he took it for a test drive. I was desperate to get a vts and my heart was telling me this was the one. After the test drive I asked my mate what he thought. He said "I can't put my finger on it but it doesn't feel right, If it was my money I wouldn't buy it"
After 3 weeks of relying on mates for lifts I was desperate for a car and I could see nothing wrong with it. Told my mate I was going to buy it anyway. Told the nice young girl that I would be back in the morning with the cash. Went home.
Mate rings me later that night at 11.30. "If you're going to buy that car at least HPI it first"
HPI'd the car and it came back as a Cat C write off. I was so close to buying that car. It wasn't up for a cheap price either. My mate never had to buy a pint for the next couple of months after that.
DON'T LET YOUR HEART RULE YOUR HEAD
