Speaking of the X6, here is an old local newspaper from 1971
Cheers, Mick.

A friend has just restored a Marina coupe 2.6 with 3speed box. He had K Mac make up a Bathurst front anti roll bar .
Engine was rebuilt maybe 100 km ago using a copper head gasket as he was wary of the lack of distance between cylinders. Loaned it to his son last week who made about 50 km when the head gasket failed.
Head gaskets are a known problem but a stock type would probably have been better. One peculiarity of the motor is that the exhaust manifold drilling’s go into the head bolt drilling’s so you have to be careful to use thick washers or you never get the head bolt tension correct.
I had an Austin 1800 once and was a good car and I drove a fully loaded Tasman up the Goulburn valley with a Datsun 1600 trying to pass but couldn’t.

Attachment 169383 Technical Bulletin from 1972 about head bolts. Those 6cyl Marina's went like a cut cat but handled like a Billie cart , They would been better off using McPherson front suspension instead of the Morris Minor torsion bar , They were much better with the telescopic shock absorber kits fitted & modified top ball joint bush kit. The early steering rack clamp's didn't help either allowing the rack to move sideways in the clamp's . Here is a couple of more Tec Bulletin's

My sister and her husband had an 1800 ute. Found several serious issue with it - rear suspension arm twisted - not up to the load on rough roads, and inadequate ground clearance resulting in a holed sump - same problem encountered with their Morris Minor "school car" and their daughter's Morris 1500.
When you say 1300 are you referring to the M1100S which had a 1275cc motor which was a detuned Cooper S motor.
The M1100 was a great car but the M1300 automatic was better than it's sister the M1500 manual . now they were a heap of rubbish , overheating , blown head gaskets , timing chain & guide failure , water pump failure , cheap trim & switches, Front brake callipers, , gear box synchro 's braking & synchro surface on the gears falling off & gear change cables getting damaged from hitting things & leaking oil. When we did a gearbox there was a good chance we would have to pull it out after the test drive because the synchro rings would brake on the test drive . The Mini's also had synchro problems during this period , they had changed there supplier to cut costs which did not work due to the extra cost of repairing the boxes under warranty . The dealership also sold Daihatsu even with the F10 4WD's having transfer case bearing problems , warranty clam's for them were les than one per month were with Leyland it would have been 100 or more.
A car salesman who's family had owned several dealerships, including a British Leyland one, once told me that even when taking customers for test drives in P76's, they were plagued with issues. He said you would be driving along and see a windscreen wiper just fly off over the roof, then on arriving back at the dealership, and a piece of body trim would be gone. He always maintained they had the makings of a good car, but just needed about another $200 spent on them in the production stage, to ensure better quality control.
Cheers, Mick.
A wiper blade flying off would be fault of the dealership, they were fitted on the predelivery but they did have windscreen trims that would fly off & windscreens that came unglued & fell out , when replacing them we used Ford windscreen kits. I had on a couple of occasions were the bonnet popped open & the safety latch had stuck open , when it happens your reaction is to hit the brake , the bonnet goes up & there is an 8ft wall in front of you & can't see were you are going. Not a good experience .
The V8's could have been a good car , I almost bought one but decided to buy a HQ Kingswood instead which was an excellent car , only main fault was the rear main they could not stop leaking , but that has been a fault on all 6cyl Holden motor from day one.
