MINI want start.

What is your question?

Last month my 2009 mini cooper s wouldn't start.It made a strange noise, A estimate came in at $ 3,886, It has 124.500 miles. I discovered the warranty ran out at 11200 miles. The shops said it needed a timing chain,gears and tenisors. Also cylinder head gaskets,there is a oil leak as well. Really need a second opinion. On a fixed income, would it be better to by the parts an just work on labor? How much would the repair cost?
