I'm flogging a car. It's old and rattly but it has life in it still.
3 guys turned up to look at it. They asked me to pop the bonnet, and then one of them asked me questions while the other two poked around under there. Then one asked me to take him for a drive, which I did.
When we got back, he asked me to pop the bonnet again and pointed out oil on the turbo, where I've never seen any before, then dipped a stick in the expansion bottle and came up with oil.
After that they were all about "Will you take £500 for parts".
The question is, am I right to be suspicious? Is that a known scam?
And also how am I going to get oil out of my coolant?
