Firstly Gonella brothers in Catford are excellent, best garage experience I've ever had.
I picked up my car this afternoon, the £300 radiator replacement included a flush of the system.
Pasquale showed me the old one and it was badly corroded at the bottom so worth getting done asap. The front anti roll bushes were replaced and the o/s wishbone was replaced. He also gave me a list of things that weren't essential but what he thought would be worth doing in order.
I have to say I thought they were great, really enthusiastic about Italian cars in general and very friendly. He also took me with him for the test drive after the work was all done, and it all seemed very smooth.
I'll definitely be going back for some of the stuff mentioned above (thanks for the suggestions), one thing Pasquale suggested was doing the rear bushes so might start there. They do bodywork as well and he gave me a good price for the rear 1/4 which needs attention so i'm probably get that done soon.
