No, I havent had it long enough. I've mentioned in this letter that its my 3rd Fiat, and my families 4th - I made my sister buy a 1.2 mk3 Punto.
I've also offered to pay for fitting of the engine, if they supply it - which I can do myself.
Oh, and its a Hyundai I30 1.6 Diesel. But I managed to make it so the insurance is free...
I would hope/imagine that showing youre not a one-off customer will help. I mentioned that the Stilo was my third Fiat & that i was planning to have another Fiat or Alfa as the replacement, but that it depended on how Fiat dealt with my concern over the spring failure.
And to be fair to Fiat UK, they certainly delivered. £300 vouchers far exceeded my expectations. My mate whos very pro Audi/VW since having no financial help when the sump rusted through completely on his 3.5 year 28,000 mile Focus a few years ago, was amazed at how Fiat had responded, giving that i didn't buy the car new or from a main dealer.
Hopefully your letter does the same kinda trick & they'll offer some assistance. Afterall, it is a hefty repair/bill.
