The 3 is now sorted under warranty, it was small pipe that had split so no drama. Had its first MOT and passed first time so pretty pleased overall. They also fixed a rattle in the door and a leaky door seal. 4 new tyres as they had covered nearly 55k! Its a decent little car to be fair, especially for the price.
The ZS has been running well, gave it a full service, front bearings replaced, exhaust bracket rewelded and auto electrician has sorted the flat battery issue. Battery was fine, something inside (believed to be a USB socket in the glove compartment was flattening it. So I am going to keep her and get rid of the ZT
