Alfa Romeo 166

* Engines: all units are generally reliable, but the quad-cam V6 needs setting up properly and easily falls out of tune, Hesitation and top-end rattles spell danger.

* Headlights: narrow lenses are vulnerable to cracking, while Xenon replacements are ΂£300-plus a side. If a sidelight blows, the whole unit has to be removed to change it.

* Tyres: front wear is heavy, especially on 3.0-litre manuals, which are prone to torque steer. Replacements are ΂£180 each; use as a bargaining point if badly worn.

* Electrics: while improving, Italian electrics are still not great. Problems include blown ECUs, sticking windows and broken air-con. Hard-to-trace wiring faults mean pricey repairs. Some parts are scarce.

* Rear bushes: a light metallic tapping from the back while cornering or negotiating speed bumps means the rear radius arm bushes are worn. Repairs are cheap and easy.
Driving Impressions
Few executive cars put driving pleasure above comfort and efficiency, but this Alfa is one of them. Even in base 2.0-litre form, it has a characterful Twin Spark engine and lively performance. The chassis is well balanced and the ride firm, while the steering is precise and nicely weighted.
The V6s are even more entertaining, and the 3.0 teamed with the six-speed box is truly thrilling. Our only real gripe is fuel consumption, which even in the calmest of circumstances struggles to top the high 20s.
Glass's View
Large cars remain unpopular, and none more so than the 166. As it is built to order, used versions can be rare - but that doesn't stop values plummeting. The Alfa depreciates fast, and after a year is worth less than 50 per cent of its new cost, dropping to 25 per cent after four years. Build quality also lets it down. That puts buyers off, but does mean you can pick up a cracking bargain. We saw a 102,000-mile T-plate 2.5 V6 with all the toys at auction for only ΂£3,400. Jeff Paterson, senior editor, Glass's Guide
Life With An Alfa Romeo 166
The 166 is a fantastic car -wonderful to look at and drive. I've had a few problems, including a new clutch and stereo, but it hasn't put me off. Marco Bevilacqua, Romford, Essex
My T-reg 166 3.0 struggles to top 24mpg, is pricey to run and isn't the most reliable car, but it was that or a Y-reg Ford Mondeo, and I know I made the better choice - for driving pleasure, at least. Nick Beasley, Chester
