Just bought the "Fiat, Alfa Romeo, Lancia Complete Diagnostic kit for Garage and Enthusiast" from scantool-direct.co.uk @ £129 delivered.
Includes registration for
Multiecuscan.
It came with a collection of OBD connectors which as far as I have read (and they say) will cover all the possible vehicles.
Connected to my 2008 X250 2.3MJ last night and bingo - really happy. Could see considerable detail and also that the garage I bought it from had not updated the oil service interval date or mileage - but when I change it again I will

. Took a moment to figure out which connector to use and the settings.
Had not realised before that you can test almost every circuit on the engine or body ECU's - such as flashing high beam, operating the glow plugs, reading the throttle pot - the works.
Highly recommend it.
