Loving it Andy...Is that wide body care on a Q4...Most I've seen have not been the wide body later model.
There were only 19 narrow body Q4s imported by Alfa UK out of 2250 built, all LHD obviously, but a few more have been imported by individuals.
The wide body Q4 was never imported into the UK but there are at least 5 here now, I know of 2 Rosso, 2 Nero & 1 Proteo (mine). Veloces once told me they imported 2 Rosso & 2 Proteo from France but no one has ever seen of heard of a second one. Alfa only made 249 Wide body versions world wide so yes it is rare in both the UK and Worldwide. The Wide body cars don't have the spec that the UK narrow body cars have, they don't have electronically adjustable dampers, or electric rear windows and most don't have air con although mine does (at the moment it is likely to be stripped out as part of the current engine rebuild).
Mine is currently undergoing a very slow rejuvenation process which when complete should end up much improved over the original. It already has coil-over suspension, larger discs and callipers, big bore stainless exhaust and rebuilt diffs. The engine is currently being rebuilt to a reliable 300-350BHP using the hybrid turbo it already has, larger intercooler, modified head and uprated cams along with a bespoke ECU and mapping to keep it all together. The current engine was good for about 280 BHP and when on song it was awesomely quick and with the suspension upgrade and 4WD it would need something very fast to keep up with it. Unfortunately the current build was not that reliable, it had too many generic bolt ons that weren't all set up to work together hence the rebuild.
