I had two Dolomite 1850s, but both were free rotters, The '74 was better built than the '78. The later one just fell apart' and interior quality was pitiful, although looked great in the showroom.
We had a Mk1 Vitesse, also totally rotten.but at least with a chassis.
I would also go GT6. I regret never having one.
My uncle had the soul crushing job of selling British Leyland vehicles in the 1970's for Hillcrest Motors in Holywell. To this day people still cross the road to avoid him.
He sold the whole range - Mini's, Maxi's, All aggro's, Marina's and the Dollop of Shite.
Cars were delivered rusting, missing doors and headlights. Couple of them had to be deep cleaned where the strikers had pissed in the boot.
Spent most of his time dealing with warranty claims than actually selling cars! Marina's were a firm favourite as they used to knock out 3rd gear.
Jacked it in and joined the local Datsun dealer - easiest job he had as the cars just sold themselves!
