I had a 164 TS, then around the time the 166 was launched swapped it for a v6 155. I had been to the NEC motorshow & was not certain about the nose on the 166, although I liked the inside. It was way out of my price range then & the 164 had reached 100k so was time to swap (although with years of hindsight I should have just left the dealer network for servicing & trusted a local dealer).
The 155 was a trusty steed, & when the air con failed, I had a few issues with the track rod ends (which led me to alfa155.com then AO.com). It seems that I was the first to have the problems & we all found out how few quick-rack 155 v6s were made & this made ePer think we needed different parts - Halfords got the right part from the 1.8 parts list after ordering a selection in & trying each one.
They forgot to fit a nonslip washer (which I found out the next year when the local Ford dealer......yes I know.....garage p155ed themselves).
Problem was the local Ford garage fitted the wrong TRE & just tightened the bolt to make it steady. When the tyres got worn on the inside, the local tyre place had a guy with a 164, and he told me exactly what had happened & didn't charge me - he told me to take it back to the Ford delear & give them a mouthful.
All this time, the 166 was growing on me, but the depreciation was soooo high, I couldn't see how I could afford to run one for my customary 3 or so yrs per car.
So, I bought an Explorer, and the 155 wouldn't leave me (I couldn't face px ing it, and couldn't sell it on no matter what). Eventually I dropped the 155 to £1k & sold it to one of the 155.com'rs for £not-a-lot.
Within a month, I crashed my Explorer (got it 100% repaired with ages guarantee), decided I wanted the 10% of life that the Explorer couldn't offer (v6 howl & sportiness) - the Explorer is still my 1st choice for a big 4x4 - and started looking for a v6 166.
I test drove a TS 166 & a TS 156 SW, decided that the 166 was better all round & worked out that only a 3.0 v6 manual Super Lusso would do.
Veloces had one soon after & it became mine. I dropped the explorer off & drove away in the luxury I still enjoy.
No regrets at any time with the 166 - the only compromise with it is that the rear seats don't drop down for big loads.
Sorry for the big post
