My 2 previous cars were a 2L Cavalier and a 2.6L Omega.
Between them they gave me 20 years of trouble free service with minimal maintenance - I had to replace the distributor on the Cavalier and a rear spring on the Omega otherwise only normal servicing.
They were both very comfortable and felt solid on the road and I got over 100K miles out of both before I let them go.
I inherited the Cavalier when it was only 6 months old and boy that car was a workhorse
I bought the Omega from Network Q when it was 18 months old with 44K already on the clock, but it was the model I wanted - big engine with manual gearbox
It went 18 months ago because it had developed a intermittent clutch problem and I no longer needed such a big car. I sold it to a guy who had a Vauxhal mechanic friend who fixed it for him (slave cylinder).
That car went like stink for such a big motor - it turned out that when his friend checked it was the BMW engine with a Mk 2 gearbox that was, apparently, the spec for the unmarked Police cars
So IMHO:
Vauxhall
2 doors
Convertable
Definately cool
