Jurdy, I did the original thread on this car which Mr Caine referred to. I viewed & test drove it - like you I was dead excited to see it in such great condition cosmetically
inside & out & amazing low miles. I offered them £5k incl new fitting new clutch as a starting point ... but they didn't even budge from £6k asking price so I walked. The seller was a decent guy but was convinced he'd get £6k for such a low mile "future classic" ..... but that was 4 weeks ago & it's still for sale.
Also I went through the sevice history with a fine toothed comb - the cambelt was changed last year by a non-Alfa specialist local county garage with no mention tensioners, pulleys, idlers etc. Also there was no reference at all to new bushes / arms / radiator etc ie) the main GTV V6 weak spots. My reckoning was everything was still original & being 13 yrs old these would go eventually & soon which would mean more expense - I tried to use this as a bargaining tool but he wasn't having any of it. I'd worry about the clutch thing as well if you think it still don't feel right.
My personal opinion was that IF it had an immaculate service history, Alfa specialist serviced, full cambelt change, new bushes etc etc then yes it prob was worth £6k (with new clutch). But it hadn't so I thought it was over-priced. The fact they didn't even budge on price really finished me off.
I've since bought a 58k miler same colour combo at £3.2k, needs a few bits doing BUT the cash I saved not buying the ADG one will easily bring it back to immaculate condition
Your call of course! But like everyone on here says - no matter what condition or year you buy one you will need to reckon on about £800+ a year on average to keep it in top nick.
