Ben,, V70 AWD leave well alone,,a no-no,, the front angle drive are VERY fragile !! Grand to sort,
The tyres on a AWD must be with in 2-3 mm of each other, so if you sidewall one, its a set of 4, otherwise damage to the angle drive
The car is NOT 4 wheel drive but all wheel drive, sorted by viscous coupling,,, also the car on -e-blag is NOT 265 brake but 240, and the early car are not that rare,
Stick to a proper 2 WD one, and you will not go wrong, if its got good history,
Look after a T5 with over 350k on the clock !!
