Ok, so maybe he could have worded the advert differently but what's the deal with the OMG! It's got outstanding finance?
He's a Kleeneezy (or whatever it's called) rep, good luck to him!
Whilst it's not for me, I know of another very successful rep from the same ilk, lives just outside Eccleshall near Stafford, he's got a very large garage / barn with every model of M5 from e28 through to an F10 along with an AMG S Class for his daily drive, his mrs drives an X5, the X5 and F10 are both on finance, the others owned outright, I'm guessing it's better fiscally to have the two cars on finance for him and why not? I know of plenty of people who have the capital to buy a car outright but choose not to.
He's clearly got the money to have looked after it, tbh, I can imagine worse sellers to buy from.
Depends if you want to buy a car from a very clear complete bser.
