I recently stripped a car using basically nothing but a halfords professional 150 piece socket set, good selection of tools and good quality, although if you could get the older style set off ebay or somewhere i would recommend that as i think the range of bits are better (e/g the new sets have no hex sockets, all bi-hex and a few other differences) i would say that is a good starting point for a tool collection and buy other stuff as/when you need them unless you have a load of money to go out and buy tools in a one'er
