Some of the things i read on here about stealers takes the mick, but this has to be one of the best yet. Well, this just goes to show that even buying form stealers is not a safe option. They bum you when buying, servicing, warranty. They just take the p1ss mate. To have no oil in is unexcuseable. The car should have been fully checked over before handing over the keys, it makes you wonder if they have done any checks at all. Tbh where ever you buy a car from there are certain checks you can do your self and this should have been one of them but then i guess when you buy from a stealer you would expect all to be ok. I guess you paid a pretty penny for the car mate so you'd at least expect there to be some freakin oil in it. If i was you i would go to the highest level with this and see what you can eek out of the b'stards. Anything could have happened from engine seizure to turbo failure, head gasket failure the list goes on. As others have said, i would take it to your nearest garage let them sort it, do ask for all the nessesary checks to be done and get them to send them the bill.
