I purchased my 1986 testarossa from a dealer in Jan this year and until now have enjoyed an amazing car that i totally love, then bang! (i knew it was bad). I am told the housing that holds the diff has collapsed, it happened as i was driving out from a junction the car give a bang and lost all the gear oil. I took the car to a local garage who told me that housing was split and advised me to contact the dealer as i had a 12 month warranty with the car. The dealer now says that this is a very common fault and he will not cover it because it is a ferrari fault and he would only cover things like clutch wear etc and estimates the cost of repair to be approx £6,000. Does anyone know of this problem occuring in early testarossa's or is the dealer trying it on?. Any info or sources for parts etc would be greatly appreciated as £6,000 is alot of money to me right now, on top of this i will have to send the box to england from ireland as i don't know anyone who might do it here and as goodwill the dealer says this is a good price to show he cares about his customers anyone else apparantely will ge £££'s more!
