    What year a6 you're looking for ? If a c5 then the best of the bunch will be the 180Bhp if diesel is your thing (comes quattro as standard) or if petrol floats your boat, then there are: 2.8, 2.7TT, 4.2 v8 all quattros- there is also a 1.8T quattro but rare and rather underpowered for the size of the car. The 2.8 quattro is slouch but smooth, the 2.7TT has massive tuning potential (but thirsty) and the v8 sounds magnificent but you'll get very friendly soon with local petrol station attendant ! I have a 2.5 tdi quattro sport (wich will e for sale soon as i bought a allroad) and its one of the best cars i ever had. They came fully loaded from factory, the suspension is good and forgiving (not as good as a 5 series beemer but not far off!) and the electrics are tried and tested. No faults on mine soo far but it had many parts fitted troughout its life: clutch + flywheel, gearbox, wheel bearings,etc. One thing to be aware of is the cambelt-they are quite expensive to do- if you use delers, find a good independent and you'll get better value for money + a job done right ! I would rather have the job done myself than take someone's word for it + you know what gets replaced and if quality parts are used. I bought mine with worn camshafts (from another forum member) and beeing a diesel specialist- i got it fixed very quick- 2 days. Trouble was i had receipts of cambelt beeing done 1000 miles befor i got the car and i did not change the belt. Shure enough the belt was a cheap Dayco belt and broke 3k later while doing 80 Mph on A13 in London- if only i've checked the make as i was aware of dayco belts snapping at the joint line (the dumbest ideea on a high torque engine). I have rebuilt the engine the 2nd time- this time i done the job properly with new water pump and all rollers an pulleys + i've fixed the aux. belt tensioner- while at it !

    Also, make shure the car has no rumbling noises from the rear diff when driven on full lock and there are no rattles/clunks from the suspension. The front and rear suspension are rather complicated multi link independent suspension and prone to failure- only use quality parts (lemforder/OEM or meyle heavy duty) as cheap susp. arms dont last 3 months ! If petrol model, the engines are prone to oil leaks (2.7 and 2.8) and they are rather complicated. There are twin lambda sensors, twin cats, coils wich fail regularly and o whole bunch of sensors. I would advise in getting someone with vag-com/VCDS to scan the car for you- could save you loads of money in repai bills later on ! From my point of view, the 2.5 tdi quattro 180Bhp is the best compromise between power and reliability (will return 40+ Mpg on a motorway trip) and the torque they provide from tickover. Throw a remap in the game and you'll be looking at 210-220 Bhp with no adverse fuel consumption. Be carefull though as the v6 tdi suffer from camshaft wear (especially if its been on Longlife servicing- walk away from those) and the injector pumps failure (cheap to sort out/refurbish by dieselbob for 550+ VAT but very expensive at dealer- 1500 quid + ). The clutch and gearbox are very strong so will take a lot of abuse but the flywheel will be on its last legs if the car has been chipped/remapped or towed with- look for bad vibrations at iddle with the engine hot and judder from clutch on take off. As i said, i'll be putting mine for sale soon so if interested drop me a pm for more details...w reg a6 avant 2.5 tdi quattro, british racing green, 180 Bhp sport, 6 speed manual gearbox, cruise control, dual climate control(usual refinements), sport recaro seats,4 electric windows,chequered fabric interior with no wear or tear, remote central locking, new clutch + flywheel, fully rebuilt engine (brand new cylinder heads, full cambelt kit fitted + water pump and thermostat+ a lot more). Everything is standard, only modifications are a allroad dual exit exhaust with exposed tailpipes (just like the facelifted models) and facelift rear bumper with s6 style rear valance/bumper trim and a slightly reduced compression ratio of the engine (helps with fuel consumption when cruising on motorway) so the car does a minimum of 500 miles on a tank full average- not bad for a 1.7 tonne barge wich can stretch its legs when booted. Only faults are a slow to close passenger front window (goes down nicely) wich migh need adjsuting and the dash is missing pixels- got worse since the cold spell but slightly better whith warm weather. The dash is a common failure on a6 but they cost 150 quid max to refurbish-do a google search... Be aware on wichever car you go for that the thermostat is a belt off job so, if the car does not warm up fully after a 10-20 miles motorway trip then the thermostat is stuck open and will need replacing wich cost big money applies to all v6 engines !
