Hi Hope you manage to get it sorted soon mate as they are superb cars, mine was a joy to drive down to Newbury this week, nearly 40mpg and so smooth! She is starting to loosen up now with over 5k on the clock, and the mpg is improving when I don't need to feel that shove in the back
On the multiple cars thing I have had up to five going at one time and have scaled back to three now

I find keeping the other two hidden in the garage helps

When they were on the drive I was constantly reminded you need to sell some of these cars. But slowly I have converted my wife to allowing me to have more than one or two as she appreciates the benefits of me spending time in the garage and not moaning about the trashy TV she likes to view

I have just had a lift installed and when I proudly showed off the new acquisition she floored me by stating "oh you could fit another car in here now under than one" ....true love
