If it is any help:
My GTV ownership experience covers 9 years.
I’ve had both a 2 litre Twinspark which died due to a fauly thermostat and WL and also, for the last 7 years, a 3 litre.
The 3 litre does all that the twinspark did without the effort and, although faster, in 6th gear can often pull away in traffic from 1000 rpm.
It still looks ex factory spec. with just the second transverse silencer removed and the flattened section under the rear frame replaced using Alfa’s 3 litre tube diameters, not the aftermarket
2 litre stranglers, but finishing with the original attenuator and tailpipe – I really needed to hear that Busso sound inside the car to assist smooth gearchanges!
The 20 year old spherically jointed rear end remains functioning perfectly as Alfa’s engineers intended (important IMVHO – but don’t ask ‘cos I’ll put on my designers hat and upset the poly men!)
Bearing gaiters are checked over for splits & lubricated every spring during the annual makeover (Garages are not reliable in doing this sort of work I find).
Overall 25 mpg + documented during my ownership. Loves Shell Nitro but now usually slurps bee pee 95 for shopping trips.
It's used as a daily driver, trackday menace (me not the car)
and runway scorcher.
Nero accellerated from a standing start up to a GPS TV of 125+ when creeping up on a TVR Sagaris at Dunsfold a few years back but I suspect that I may have gas flowed ports. Who knows, it’s a grey import with no pre-history!
Reliability? Good as any IMHO. Only probs I have had:-
Help from rescue service when MAF sensor packed up about 5 years ago but it got me back up the M5 in limp mode.
Early days the intermittent airbag light drove me mad for a couple of years until I found it was due to a Telepass wiring fault. (so obvious)
Interior boot release disconnected (only discovered when I had locked my keys in it
)
Front tyres on trackdays - Pity Alfa used Macpherson front struts. Mine’s got Konis and some say a Q2 would help but I had a ride in one with the Alfaholics GTV kit on it but didn’t rush out to order one ‘cos a few pairs of rubber shoes iz far cheeper and it seemed no quicker through corners (subjective of course).
Tyres are important for handling. I used the underrated budget Hero 50% until they stopped importing them & now have Vredenstein 55% because of the motorway potholes mainly.
Would I buy another? YES. It does everything a
2 seat GTV should do and more.
