I'll follow your off topic with further off: I once got a super deal on a car I bought it not knowing what was wrong, but just that it had engine trouble and would only run when cold.. then slowly get worse until it died. Well I started it up.. drove away and it started to get mor eand more sluggish..engine laboring. Pulled over, checked the oil: all frothy like milk. Well.. drained it out to find it was Double the recommended amount. Far as we could figure, the last oil change they probably drained.. an filled.. and forgot they filled.. and filled again!

anyway, new oil and a new cat (piles of oil going down your exhaust ruins them) and away I went.

It was a rabbit convertible (not the cabrio.. but the original rabbit one) so I added some aluminum siding and made a THING replica and took it off roading.
