Wow, just realised I haven't posted in here in a long while!
In early December the 406 finally started playing up, then someone smashed the rear screen over night and the MOT was due soon. A friend offered me his 525d for a good price so sadly the 406 went over the weighbridge, but I'm very happy with the 5 series. Super comfy and less painfuly slow/floppy to drive. The 6 pot's super smooth for a diesel too.
The Porsche has been off the road for the winter. I'll probably pull the head off to see if the noisy engine's the result of anything more sinister than the cam followers. Hopefully not, in which case I'll try and grab a second hand head for it and get on with suspension fun.
Dan, I'm glad you got away with such little damage! Very lucky. We're the spacers hubcentric? I've run 15mm slip on hubcentrics without ever having the bolts slacken off. I guess the wheels face thickness could effect bolt length a fair bit though, mine were pretty thin.
Jardo, massively gutted about the pop. I do hope it see's a 2nd life!
