Smoking its tits off, you think I new about it smoking its tits off. It only did it past 7000 rpm, so I'm told! . I told you I hardly drove the car when I owned it. And also told you I didn't drive it past 7000rpm as I don't thrash my cars!
I cannot tell you things I don't know about. That's why I told you get a grip. You never once informed me about changing engines until I noticed on the forum. Now you want money.
I told you all that I knew about the car, you test drove it and you told me it smoked a little, you were happy to proceed with buying it.
It's now came to my attention that the previous owner changed the engine, which you knew about before buying it.
