Apologies Haydn - back to your your post!!! Which reminds me - would you consider getting one abroad / LHD? That source offers a far bigger choice of 164 QV's than here. Googling "Alfa 164 for sale Europe" brings up quite a choice. LHD certainly wouldn't put me off buying a rare car.
Obvious two downsides - they're usually more expensive over there, and it's a slight pain having to go over & pick it up... so just make a holiday out of it! Also car haulage / transporter co's will bring it over for about £500.00, at least that's what I was quoted when I seriously toyed with the idea of buying an Alfasud Sprint in Europe a few years ago.
Good idea that, and there's always the option of doing a RHD conversion if you're up for a bit of a challenge.
There's occasionally the odd original q4 for sale in the more northern countries too (haven't seen any in Italy yet) which could provide even more incentive to go for LHD; chances are the 'box broke on the 'Savali' because there was too much power going through it; I bet if it had been FWD it'd have lunched it's diff just like the 3.2 gt/gta/gtv do.
Edit: Or, for a very similar if somewhat less pretty version of the 164 with an even more exciting engine, how about this?
Edit2: I'd better point out I'd love to have a RHD 164 and went on a serious search a few years back, but every one I came across was either so rusty it was this -><- far from being in donor territory, or supposedly in 'showroom' condition and dramatically overpriced.
