Local service garage has done the front springs and MOT, but told me he left the rears because he could not locate springs, apart from Fiat at £100 each. Will pick it up soon, but look at doing rears and Bilstein shocks. This could mean rear tracking, which has been perfect on mine after being reset at a 15000 miles recall, long before I got it.
As expected Fiat customer care was totally useless, wanted me to transport the car 16 miles to a Fiat dealer for him to inspect the spring, a decent maker would have had a field service engineer do that anyway. I suggested that the spring would still be available after replacement, but that was off the script.
