I'd agree with all that.
I bought my 164 on a whim because one came up locally for £750 on an M plate with 114k on the clock.
The interior has held up perfectly and is as new.
It had a few minor electrical grumbles, no more serious than a slightly disinterested electric sunroof. But this was as the car had been standing for a year or more. The MOT for that period shows it did only 6 miles. With a bit of use, as I find with Alfas, minor nigles seem to magically heal up by themselves. They don't like being left unused.
Quite right about a post '93, it is simply not economicly necessary to consider one of that age and a Super will always have a better spec. My understanding is that structural bits of the rear suspension can rot away. I have seen more than one of that age driving around with it's arse on the ground and nose in the air. Probably being used as a disposable motor by someone, shame.
My 164 is the cheapest but best car I have owned, I have had several new saloons and a 200SX turbo amongst others. The 2.0 TS is a lovelly unit and I was delighted to learn it uses cam chains not belts. Engine note is lovelly. It is good off the mark but not fantastic, it is geared for mid range and top end grunt. With the VVT this make for excellent and suprising overtaking acceleration for a 2.0.
Things to look for are no different than any other fwd car. I always recommend good tyres (they keep you alive) but if there are cheapies on the front you WILL get torque steer which can be disconcerting on adverse camber roads whilst overtaking under power.
I have a full set of Avon ZV3s and they are excellent.
Handing is communicative and entertaining, but be aware that 164s get their body roll out of the way early in turn in and firm up rapidly from then on, unlike most other cars that do it the other way around. There is also more torque and grip in third than you might immediately think, so kinder fast driving is possible.
I got drilled and grooved discs and pads from EB spares and they are excellent, probaly cheaper than the Alfa ones as well. I have filled up with Selenia for the first time and would say that it is a must.
Any money I have spent on it has been due to choice, ware (rear shocks + springs + clutch) or damage (radiator + back box). The only show stopper that I can blame on the car was when the instruments decided not to work one morning. This was just a fuse that I couldn't find and was rectified easily.
My maintennance bill might sound high to some people, but I work it out at cost divided by mileage, this works out to 10p a mile in my case (and is getting lower all the time). It is the cheapest car to run I have yet owned.
164s are dirt cheap, hold out for what you want because one will come along. You should be able to get the moon on a stick for £750 - £900. Have a look on www.autotrader.co.uk
there is usually half a dozen or so on there.
A 164 is a lovelly, capable car and the low purchase price on such a highly presentable exec car will make you smirk when your friends mention their monthly repayments for their jelly moulds! (Plus main dealer servicing & depreciation. Ouch!).
I, and others no doubt, will be very interested to see what you decide on.
Good 164 hunting.
