For what it's worth just back from a fab visit to DMS & Rob said that the Bosch ECU could detect 97 v 95 RON 'after a full sweep through the rev range'. Once 'happy' it would default to the 97 power curve - apologies if any of the above got lost in translation!
Without wishing to prolong this lost opportunity debate I did get in touch with the Maserati Club some time back (initially with no response) to enquire if they were looking for cars to make up the '100' - I eventually received the response that Carfest was not on their radar & that there was...
DL put me onto them when I had my RTA last September. Very impressive same day response with a replacement M3 Cabriolet & apologetic that it wasn't a Maserati! Paperwork all handled efficiently, the weak link was DVLA!
At last ...... it's seemed like an age away from the marque after the 4200 was written off last September but I put down a deposit today on a 2011 GranCabrio from HR Owen & can't wait!
Tried a lovely GS today & found the ride a fair bit firmer than the 4200. Sadly a bit too much for my dodgy back - now looking at a 2009 5.0 XK & planning a trip to DMS to get it 'tweaked'.
Just heard this morning that it was assessed as a Cat C, (beyond economic repair). Now just the usual discussion over valuation - the opening gambit was £14.5K (hardly surprising it was a Cat C at that valuation! - only done 31K). I politely suggested he spoke to DL and we would chat again...
