Sentinel 280

I'm going out on a limb here, but the number 280 coincides nicely with a wheelbase of 280cm, just about right for a 110" wheelbase mid-engine car. Lots of room for a mid-placement Viper engine mounted on a G50 Porsche transaxle!

Sentinel 400

Ahh, if limousines just looked like this..... The designation 400 might be based on a wheelbase reference, since 400cm is about 158" and photoscaling based on a 74" driver height would indicate this wheelbase to be around 160".

This design looks as if it might have had a slight influence on designs at Ford during the 80s, like some of Jack Telnack's work.
