Got my 3.6 back on the road today. It had badly seazed calipers and some running and electrical problems.
All sorted now.
Took it for a drive and its such a different car to the 3.8. Not worse in anyway i'd say, just very very different and just as much fun to drive.
Its going to be my daily driver now.
Just need some help on getting some replacement front and rear calipers for it as the pistons are very very badly corroded and its only a matter of time until they seaze again.
