I've just been on the phone to Abarth trying to persuade them to let me have it done at a Fiat dealer, but they didn't seem too keen. I've got to wait for an 'executive' to call me back. Judging by the last time I rung to complain that my 4 month car was rusty and several features don't work.....I'll not be holding my breath. If anyone has any luck getting them to agree to a Fiat dealer, please let me know.
