Re: hi there.
Hi there Damon, I'm just up the road at Cuxton. What year is your Spider? Apart from the obvious engine things - cambelts, variators, water pumps, thermostats, radiators - the other things to look out for are - rear suspension bushes and subframe corrosion (MOT failure), front suspension, brake discs and pads. Also electrical gremlins.
There is a good independent Alfa place in Canterbury, who know what they are doing, and are much more reasonable than main dealers. They are Mobitech Engineering.
Good luck with your new purchase, looks like you may have bought it at the right time to enjoy it.
