Consumer rights - used cars

[harry01hog]

Hope somebody on here can help me.

I purchased an (expensive - £45k) used car 6 weeks ago from a well-known marque specialist. Obviously I cannot name them on here. The car has a oil leak which following checks by the specialists local mechanic is the sump plug which has been cross-threaded and will not seal properly. The mechanic has tried a new sump plug and washer but this has not worked - the sump hole thread is rubbished.

The garage I bought the car from changed the oil before I got the car, so obviously one of their mechanics has cocked up here.

What are my rights - to fix the problem will require a new sump and the removal of the engine - estimated bill at least £5000 !! I am waiting for the dealers to advise what hey intend to do- but would like to have some ideas before I hear from them as follows;

Are they legally responsible for the repair - warranty car only covers £1000 ?
The car has only done 500miles since I bought it - could I reject and ask for a refund- I am concerned that removing the engine will disturb all sorts of pipes/wires etc and could end up with numerous leaks/faults later which would be my problem to solve ?
Could I ask for a loan vehicle if they decide to repair it?

Hope somebody on here can help me.

Thanks guys

The mechanic is one who works for the garage I bought the car from - he does warranty and service work in this area.

I'l see what the garage want to do now

It appears my concerns were groundless. The dealer I bought the car from has authorised a new sump to be fitted at their expense. Apparently on this car (a Bentley Arnage T) you can replace the sump from below without removing the engine. About 6 hours labour apparently. The mechanic has confirmed I should have the car back towards the end of next week.

Thanks for the prompt responses anyway guys.
