Hello Mark McGowan, i am a lucky owner of one of the european 101 cars.
My car has always been at ex-U.k. Roush representatives, now monotone company in Brentwood , near London, United Kingdom, for all the maintenance work.
Mileage shown, after the service in U.K. was completed, was 12000 miles, when i first drove it really very fast on a german motorway (Autobahn), heading southfrom Kassel towards, then the american airbase near Frankfurt airport, i could see on my tom-tom-navigation unit a reading of 351 kms/h, i was in fifth gear and"the pedal was not down at the metal". I have to admit thatthe Autobahn there is slightly downhill from Bad Homburg, but not really steep. Another time i let roll my car, with the gearbox in neutral position, and due to the then fitted tyres i could only get to 120 kms/h "rollingspeed" , i have to tell you, that i am using the Bridgestone tyrecombo with the 345-ers on my rear end, the frontone' s, i am not sure with the exact dimensions i have. On my standard forged BBS, sold to me,when car came from Roush to my dealer in Switzerland.
After that trip, Dave Jones , now Montune in Brentwood, fitted an another pulley on my charger.
I also know about the accuracy, of all GPS based navigation units, but i passed on my fast drive a Bugatti Veyron and met this driver later, when we were both refueling the two cars.
He admitted, that i have passed him, to his own astonishment, with well over 340 kms/h in the Bugatti's odometer!
I am curious to drive my car once to the absolute top speed, for example in Nardo, as the speed indicator on the Bridgestone used now, is good f. 400 kms/h
with F-GT-greetings ! FelixIbizaSwitzerland
